Usually in the last color band we find gold or silver colors which are at the end of the resistor and when we calculate the value at that time also we take the gold or silver color as the last one
we take the first color as the color which is opposite to the gold or silver colors and then from there we start as the first second third and forth band of color and forth has to be either gold or silver and it is always the last
To summarize just remember that the gold and silver band are the last color bands
You forgot to mention this many people in your comments have the same doubt
Important note: Differentiate between capital and lowercase lettes to describe the numbers. 1 mOhm is actually equivalent to 0.001 Ohm, while 1 MOhm is equivalent to 1,000,000 Ohm
For everyone wondering which end to read resistors from I found this online which was helpful:
How do I know which end of the resistor to start reading from?
• Many resistors have some of the color bands grouped closer together or grouped toward one end. Hold the resistor with these grouped bands to your left. Always read resistors from left to right.
• Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.
• Basic resistor values range from 0.1 Ohm to 10 Megaohms. With that knowledge, realize that on a four-band resistor the third color will always be blue (106) or less and on a five-band resistor, the fourth color will always be green (105) or less.
My man!
I'mean seriously impressed by your skill for teaching dude. Simple and clear. Very good!
Oops! *I'm
You sir, are an inspiration for the rest of us wannabe electronics hobbyists. Clear and to the point explanations without too much technical mumbo jumbo. Thank you and keep up the good work.
how do you know what side of the resister to start reading the bands?
I was wondering the same thing, so i investigated it: Apparently the first band is closer to its end and the tolerance band is thicker. Many say though, this not being something explicit so they prefer to measure the resistor.
"People don't think the universe be like it is,
but it do"
-Black science man
From the side that has more stripes in the row. The tolerance stripe is presented after space. It can be usually silver, golden, red or brown. For me it is very hard to associate colors with numbers, so I prefer to use simple system. 4K7 - 4.7 Kohms - 4,700 ohms. 3M3 - 3.3 Mohms - 3,300,000 ohms. These stripe are just confusing to me, I would try to use it only if I have no schematics that explains the resistor values.
Sometimes it is really hard to tell especially with precision resistors. When in doubt use your multi meter to get a reading to verify what you think it is.
I agree that encoding the resistor with "4.7k 2" would be easier to recall, simpler, and arguably shorter than yellow violet orange red (did I get that right even?) and pay attention to the spacing and if there are two or three number bands before the multiplier and tolerance.
Thank you! Clearest video on resistors I've seen so far!
Although, I'm not sure where to start reading. I know a gold or silver band goes on the right side, but as you probably know, not all resistors have a gold or silver band
*Summary:*
- a resistor is a component that you can put into a circuit to provide additional resistance to the circuit
- the color bands on a resistor tell you the strength of resistance (in ohms), which is usually a range (e.g. 10 ohms, plus or minus 1 ohm, means a range of 9-11 ohm)
Now were cookin!! i do electrical work and have hobby's dealing with repairing circuit boards. Your videos are really helping me learn electronics!! keep up the good work!! thanks a bunch!!
Just started watching these tutorials - very educational for me as a beginner - thanks so much for creating them as I appreciate it!!
THANK YOU FOR TAKING THE TIME TO MAKE THESE VERY HELPFUL VIDEOS!! I have been interested in electronis for quite a while i would pick it up and drop it, but these vidieos might be the push i need to really get into it as much as i would love to. i recently ordred a nixie tube clock kit in the mail , the instructions might as well be writen in chinese. i look forward to learning more and eventually putting togather my clock without fear of burning my house down. you are a scholar and a gentleman! thank you again good sir.
It is no wonder you got into electronics with a name like CodeNMore. Excellent videos.
The way this guy teaches blows my mind. Respect and i believe you have nerver learn how to teach cause this way of teaching is gift from the must high. Best regards.
I was working with resistors and i need a really high resistance, i forgot i was colorblind so i grabbed what i thought was what i needed, but it was really low resistance and the resistor blew up. Lesson learned. I know double check w/ a multimeter
Lol, that happened to a friend of mine too, he almost failed electronics. And that helped he figure out he was colorblind! Resistors saving lives.
Is this guide going to be continued? I have found it to be very informative so far!
Your videos are a great help! I will definitely score great on the electronic part of the asvab!
This video was really good I tried to find so many videos but this one was the best!
Thank you! I really needed help to understand this clearly! This is helping me!
Thank you very much for sharing, I really learn new things such as looking at electricity as current through various sizes of pipe (resistance)from water tank , and today you teach me about meaning of colour of resistors which in the past I had no clue at all.
Thank you so much for your teaching! I can't wait to go to the next tutorial...
this is the best videos i have seen please do not stop...
Saw this shit a few years back glad to see you're still making videos
thanks for the help. This is a really great set of videos!
thank you so much for these videos!! it has helped me clear up a lot
Excellent video, thanks a lot for your effort
most accurate: gray. less accurate: silver. Why god why
And then yellow and gold. :))

Dick Richardson give it a rest mate.
LOL
@@0believeinjesus9 yes, thank Jesus Christ, and may he bless the commet section with electrical knowledge over night, lol
I have enjoyed the videos. Hope to see the next one soon. Thanks a lot..
Glad i found this tutorial in 2020
and me in 2021
and me in 2022
Nice videos man I'm Learning alot by the way what screenrecording do you use?
Very well done! How long until the next vid?
Great tutorials, just one question, what side do you read the color bands from???
Thank you so much for the video!
please continue this series :)
I think a very important point has been missed as in which way round to read the resistor bands in the resistor but otherwise enjoying the vids.
Thx great video man. Learned a lot!
Saving me in my circuits class right now
man you are amazing!
i really appreciate it !
you helped me a lot
nice way of teaching. love it buddy 😘
At 7:34 in your video discussing resistors, I have two questions regarding the images of the sample resistors. Firstly, how do you determine which band is the leftmost band? I ask because in your photos, the orientation could be altered so that the leftmost band appears on the right. Secondly, why do these resistors feature different colored backgrounds?
It would be good if you could explain how to calculate the resistance with a 5 band resistor. This is a complete mystery to me. Other than that, these videos are very helpful.
its in the video tho.
where should we connect the resistor in the example at the starting of this video.is it to the side of the negative terminal or to that of the possitive terminal?
Hey, I had a couple of questions. First does adding more resistors in line of the same value change the resistance or does it stay the same? Like would two 100ohm in a row still be 100 or would it be 200? Also does it matter where in the line the resistor is? Like does it need to be on the negative or positive side of an LED? Thanks! Loving these videos!
where is next video?plz update.the classes r very excellent
Super helpful! Thank you!
Brilliant, i forgot all this from school......thank you.
I would like to ask one question, since one end of the resistor looks just like the other, how do you tell which way it goes when you pick it up? Do you know because this closest together on one part that's where to start?
I have to take notes for school, and the chart that you are using in this video is very helpful. Where can I find it?
google
Good camera! I have to use +6 magnifier glasses to see the lines on the resistors.
you are an excellent lecturer
Very informative lessons here, bro. Takes me back to my electronics class (which I didn't pay attention to, BTW). Now that I'm older, I'm taking interest in a lot of DIY projects like radios and speakers and your lessons greatly benefit idiots like me! Question: how do we know that we're not reading the resistors upside down reading them from the wrong band side? I'm subbing, BTW... and taking down notes this time! :D
Good question, so whats the answer?
Here. How do I know which end of the resistor to start reading from?
- Many resistors have some of the color bands grouped closer together or grouped toward one end. Hold the resistor with these grouped bands to your left. Always read resistors from left to right.
- Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.
- Basic resistor values range from 0.1 Ohm to 10 Megaohms. With that knowledge, realize that on a four-band resistor the third color will always be blue (106) or less and on a five-band resistor, the fourth color will always be green (105) or less.
Thanks a lot sir. Good work
Thank you sooo much, these are great
Thanks so much for these vids
Your a awesome teacher dude
Probably a really dumb question im sorry, but how would you know what side of the reisistor to start reading the bands from? i see in your first diagram you drew, you spaced out the last band far away from the others but the real picture of the resistors look to have bands close together
How do you know whether you have positioned the resistor the right way and not the opposite?
So it is possible to make one resistor with at least 2 ways? In example a [black, red, blue] would give 2mohm as well?
hi teacher, how do you know which resistor to use for our light bulb or other device?
Super clean nails - always appreciated.
plz continue with the series i want to learn how to make a 8-bit computer
Excellent!
I'm kind of confused. How do I read the 5-color one since your chart doesn't show it? Do I read the 3rd color as the 1st then the multiplier?
What I mean is this: with a five-color resistor, I'll go with 1st 2nd 1st multiplier tolerance, according to your chart's top row. Is this correct?
How do you know which side to start from when looking at the bands
Great Videos :) Should have more views!
how do you tell what way around to look around at resistor .. I. each if it's upside down there totally different
How do you know which color to start with and which color is the tolerance?
thank you soo much for this contents.

good stuff man
Thank you for sharing your knowledge
Voice and accent,so good.
How do you know the gold band was the last band not the starting band?
love ur videos
I see some resistors are rate 1/4Watt, 1/2Watt, etc. How do you determine what wattage value resistor to use?
How should we go through the resistors to know the resistance by color codes, from left to right or right to left?? And from which side to start the first color?!
and how to know if the band of the resistor is in reverse color?? cause i find a 5 band resistor in internet but i cannot find what to multiply first because all color band almost have the same spacing....it have red and purple on each side...
please how do i know which direction to read the bands from? the shape is the same so what if its flipped and I start reading from the other direction, it would give me a different amount of ohms. So how do I know which way to read from???
what to do if you have to reach a certain resistant value but dont have a sibg resistance that reach baut hast to resistance added together to reach said value?
how you know what color band on a resistor is the first and not the last?
nice video!
How do you know to put the decimal after the 1st 2 bands? Because the 3rd is the multiplier ....Right?
Slightly dumb question but from what side do i read the colour bands; i mean how do i know im starting at the correct side reading left to right
David Mills the tolerance is always spaced out from the rest and you read that last
How did I know you were going to do conversions....because your tutorials are very flowy lol. Good job.
How do I get the resistors colors chart from the website?
how do you know which orientation a resistor is in before reading?
How can you determine which end is the beginning ?
Hey! Just asking what to do if you have to strong resistors. So strong that mine led's wont even light up(Tried hooking up my leds with mine 9v battery. exploded right away:(
How to build a wailing siren and components required?
what is the color code for purple band in the resistor bcoz is not in the color code band chart
You are a treasure 🙏🏼🙏🏼
This video says that when 5 band resisters are used, the third band is to be interpreted as a "regular digit," but it's used later in the video to represent the tenths decimal digit. Is this always the case? Five bands never use the first 3 to yield a number in the hundreds? And, the third band takes the value in the "Multiplier" field, while the fourth band also takes the value in the same field?
very knowledgeably guy
thanks
I searched resistor color band graph on google and there are F G D C B J and K next to tolerance's percentage. What does that mean?
Is their only 4 color bands in a resistor?
How do you read the 5 band resistors?
Great. Thank you.
Very awesome
how to know which is the top and which is the bottom of the resistor?? both way it looks the same... btw grt video...👍
how do you know which sideofthe resistor is tolerance andwhich is digits
How do i know the value of the third color?
