At Manocha Academy, learning Science and Math is Easy! The school coursework is explained with simple examples that you experience every day! Yes, Science & Math is all around you! Let's learn every day from everyday life!
The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). Current intensity is often referred to simply as current.The I symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating Ampère's force law (1820) The notation travelled from France to Great Britain, where it became standard, although at least one journal did not change from using C to I until 1896.
Thanks for this info😇😇
Mr Time Traveler
Charge=Q=3C
Potential difference=V=6V
Work done=charge×potential difference
W=3×6
W=18J
Manocha academy is better than byjus👍👍
No
@@abcdefghijklmnopqrstuvwxyzpqrs yes
@@advaitnn2136 no
@@abcdefghijklmnopqrstuvwxyzpqrs yes because if you didn't Subscribe to byjus it will call or message thousands of time so thats why I dont like byjus
Absolutely yes
Sir my humble request to u sir that can u make a video on why sky is blue in colour with detailed explaination.... i searched many youtube videos but i am not satisfied sir... so i am asking u sir... u teach in a practical way that is very useful for us to learn sir..... pls sir make the video on that topic...
Scattering of light
Why is sky blue? - czcams.com/video/pO7yXuk-Dgs/video.html
By Manocha sir

By the way without going to school sir taught us in such a way that no need to do the online classes from the school .
Thanks a lot sir .Best teacher than in school
It's my pleasure
Sir, I am 45 yrs old but learn a lot from you which our teachers were not able to teach us. Thanks
The work done in moving 3c of charge across a potential difference of 6v
the answer is W=V.Q=6.3=18J
If I hadn’t seen this man’s videos I would 200% fail my physics exam thank you so much sir
Sir thanks for teaching us who don't have teachers in this hard time..I really learnt a lot of physics and chemistry just for you 🙂
How can we know that glass rod get postive charge and ebonite rod get negative charge? Hope u will surely answer my question
i too never understand that which substance will get what charge
When the glass rod is rubbed with silk cloth, then the electrons of the glass rod transfer to the silk cloth, that's why glass rod will get positively charged.
and when ebonite rod is rubbed on wool, then the electrons of the wool get transferred on the ebonite rod, hence ebonite rod gets negatively charged.
(since electrons carry negative charge)
@@prasoon7916 ok thnk u
Please search triboelectric series after that you can say that a metal has which charge
W = C x V
W = 3C x 6V
W = 18J
Sir please explain about kirchoffs loop law and sign conventions of current, resistor, emf of battery please...
Your teaching is amazing !!! 👌👌
Thank you! 😃
Does the electrons separate from the atom to move in the wires cuz the protons and neutrons doesn't move? What kind of atoms are they? Hydrogen helium?
THANK YOU SO MUCH SIR! This video cleared all the doubts I previously had, regarding current.😊😊😊 WONDERFUL EXPLANATION INDEED....
You are most welcome
UNBELIEVABLY GOOD CLASS...THANKU FOR THIS VIDEO...
You are most welcome
sir can you please give a class on ressistivity and heating effect of electric current?
Thank you sir for a great class
You are welcome
Ae Manocha tui kothay thakis kolkatay
Sir one video on battery, how it creates potential difference and the reason for Direction of flow of current.
Sir thank you for the great live class
The live maths class on Wednesday at 8pm could it be on simultaneous equations please sir
Super explanation and l really enjoyed this session
Glad you liked it
Sir great teaching...... :) Really make physics and chemistry intresting to learn
ur explaination is amazing....u r d bestt
Sir you're superb you help me a lot during Lockdown when there is no proper arrangements of online classes and study materials ...😊......Thank ...U ...so.much...Sir
It's my pleasure
Sir but in our book it is written that current flows from positive to negative terminal of cells
Sir the answer of the homework question is (c) 18J
Sir, seriously you are the best teacher which teaches us like a friend. Thank you so much
It's my pleasure
The si unit of electric charge is coulomb
Sir ji , kya Mera concept clear hai ?
Hm jabh bhi baat karte Hain current ki toh voh positive to negative hota hai ?
Agar aisa hai toh electricity ki 2 types main hm ek static electricity aur dussri conventional current manege ?
Your teaching is amazing👌👌
Thanks a lot
Work done = Force * Displacement.
Work done= 3V * 6V
Work done= 18J
Thank you sir for ur class...ur class making us easy to understand and ur are the best comparing with our teachers .🙏 And try to say biology class also sir we are also interest in biology sir...once again thanks for ur class sir 🙏....
Like seriously I also need it
Biology is easy , all you need to do is by heart what's in the book
1.5V the unit is writen in the cell
Your explaination is very good
Thanks
@@ManochaAcademy your welcome sir
We should use the direction of electric current as same as the direction of flow of electrons because at that time scientists did not knew about electrons. But we know so why we are doing same mistake even though we are aware of it?
Work done = 6v*3c which is work done is 18J
Ans: as we know , "V=W/q" so rearanging then it becomes as "Vq=W" so W=6×3=16 and in SI units 18J. It was so easy.
Talk about the operation of lightning conductors
nice teaching sir i like your teaching way i can understand very easily i love chemistry ,but i don't like physics when i am listening your class then i am getting intersted in physics subject tq very much sir
Glad to hear that
