Question 1

There is a flood situation happens, and an expert gives advices to defend from electric shock. One of his advices said that “in case that you have to force a way through water, we might cannot check ...

Question 2

If photons are the carriers of the electromagnetic force, why isn't electricity made of photons? Or, why isn't every electromagnetic effect described in terms of photons, if they are the ones carrying ...

Question 3

I have a few questions about principle how van de Graaff generator works. To avoid confusion I will use numbering from the wiki picture: [ADDED LATER #1] See also here for nearly identical ...

Question 4

I understand that solar panels generate electricity by converting photons from sunlight. This made me wonder whether it would be possible to use other types of cosmic radiation, such as muons, to ...

Question 5

I have a gold leaf electroscope which works very well the first time. After thus it stopped working. Even when the gold leaf moves, it moves very less. How to fix this?

Question 6

When we touch a conductor with eddy current flowing on it, will we get a shock? Because in my opinion there's an induced EMF due to which eddy current flows (assume the conductor is in the region ...

Question 7

Hello I am a 12th grade student preparing for Jee and just started learning about semiconductors, I wanted to ask that in pure silicon semiconductors, when a electron is released and goes into the ...

Question 8

In the article What's the Difference Between Fog and Clouds? it says: Clouds and fog both form when water vapor condenses or freezes to form tiny droplets or crystals in the air, but clouds can form ...

Question 9

Is charge an intrinsic property of matter? For example, I can induce a static charge and also we see ions which are charged. But from a fundamental aspect, is it an intrinsic property of a substance?

Question 10

Studying electricity, we come across the ideas of voltage and current. Current is fairly simple to understand as its simply the rate of flow of charges in unit time. However, the cause for this ...

Question 11

If the field is directed from lower potential to higher then the direction of electric field is taken to be positive or negative there is a lot of confusion, the famous unacademic site on google ...

Question 12

Electrostatics Knowledge of insulators and work function

Question 13

I was remembering how as a child I powered a Crystal Radio by just running a long wire 3 or 4 times around my room architraves/cornices. And was wondering why the same principle couldn't be used to ...

Question 14

I often notice that the electrical fields in my home created by mains differ in dependence how close the grounding conductor is to the measurement antenna. I haven't managed to model this yet, so I ...

Question 15

Hi, Is it convenient to ask the following question about eddy current levitating coil? Suppose the rms value of ac sinewave current current in the coil/solenoid is kept constant , but the frequency is ...
