thank you! very useful explanation

I just needed literally the first sentence. Thanks.

this is simple explanation, thanyou

Hello 5yr ago video...I have a question: I will be using pyramidal horn antennas with an LNA and a spectrum analyzer to scan in a 360 degree azimuth to look for possible interference in the X and S bands (2GHz and 8GHz). One of the requirements is to "Calculate cold sky noise temperature at 10 degree elevation." Would you (or anyone) perhaps know how one does this? Is this simply measurable somehow? Google doesn't get me too far...

thank you very much

Please say in hindi.

Hello, very informative video about the complementary VCO, one question I to see the open loop gain in nmos or pmos is VCO is simple u just put a differential stb probe and u see the open loop gain, but with complentary VCO how u can break "the open loop", because now you have 2 pairs with negative res.

Thank you for posting a very clear explanation!

Please explain ja 560w solar panel coefficient Laval?

Anybody can tell me charge controller se dono ki energy combine kar sakte hai

Good information about EVM

Sir I want to ask a question how solar radiation depends upon irradiance give me any eqn Or theoretical explanation or link

Why you couldn't put an object instead of a mirror in the set up of the Michelson interferometer?

In the PV Tracking Farms / Two Axis Tracking slide, the Solar Panels in the upper right image. are not even pointing at the sun! So, of course their shadow is "narrow". Did you even look at that photo? What time of day is it? Noon? Well of course, the shadows are shorter then. Show me this photo at sunrise and sunset.

I completely disagree that higher latitudes have *shorter* shadows. I am at a high latitude, and I have very long shadows. Then you say, taller arrays have shorter shadows. What? No, taller arrays have longer shadows. The more vertical the array ( ie taller) the *longer* the shadow. You are very confused about higher latitudes and shadows. Shadows are much shorter near the *equator* , while shadows are much longer at higher latitudes. I don't think you "know" this subject very well.

thank you professor. please what is the meaning of (1-x)

How can an electron donor be a positive electrode? 🤷🏾‍♂️

thank you sir, amazing explaination

Thank you for this simple explanation

Thank for more lession

Thank You Sir for the best brief yet comprehensive explanation.

nice

After recently studying some of Leonardo da Vinci‘s inventions, I noticed that his automaton used pulleys and it seems that he had the right idea.

Very nice explaination Sir. Thank you

Very simple and concise explanation. Appreciate it!

Thank you ❤

Thankyou

is there any paper/reference for explaining that formula?

thank you

dude I'm trying to get some 40k dielectric constant polymer film. maybe its all bought out or called more specific names than I can find right now

Hello, I am running DC fan with 12v adapter. Now I want to connect a 100w solar panel to the same fan. The problem is of course if during night I run through adapter, it will also feed solar panel if someone forgot to switch off the solar line and vice versa. During the day if solar panel is running the fan and someone turns on 12v adapter that's connected to the mains, I am not sure which power fan shall be drawing, solar or mains? I got Chinese 10A diodes also referred to Schottky diodes but it would become super hot. Someone told me these are actually 5A diodes but marked 10A. Therefore I soldered 3 diodes together and should I put in the positive wire as you did but close to the panel or close to the fan? In addition, similar diodes should be also connected to 12v DC adapter's output positive wire? I don't think heat shrink would cover 3 diodes soldered together. I am thinking of a hack to make housing for the diodes. Any suggestions welcome.

Boring as hell. I rather be in high school again taking a pre-SAT on a Saturday

The signal that results in Havana Syndrome apparently also suffers fade when outside and its raining.

awesome explanations

What a great job.

Pls make tutorial on rectenna as well

Huge problem: solar doesn't run for 24hrs/day. So expected energy output over its lifetime can't simply be its capacity multiplied by the lifetime. It must be adjusted to reflect the operating window.

degree kelvin or should it be just "Kelvin"

great sir

Graphics are tough to make out what part of spectrum is used, but there's probably already metal and or element that resonates at the frequency of the wavelength used passively...Have to search more videos what part of spectrum that is. Probably nickel or something cheap does it already. Zinc one them.

great lecture

Thanks for this explanation..

Great explanation! Thanks

very helpful

We can work together to see, professional hardware providers and software!

Solar panels have bypass diodes, not blocking diodes. Two different things

Thank you. I've been searching to understand this and you explained it very well in terms I can understand

We have 1000v/2000v wire but not panels just yet. Even 9000v wires but no panels
