When capacitor is connected to a battery, current starts flowing in a circuit which charges capacitor until voltage between plates becomes equal to voltage of a battery. Since between plates of a capacitor there is an insulator/dielectric, how is it possible that current flows in a circuit with c...

Why does solid and hollow sphere goes through same expansion in volume when raised to the same temperature? Please explain it at molecular level with an example and not via the formula

I'm neither a professional in cryptocurrency nor physics but an interesting idea occurred to me. Bitcoin involves mining which generates a lot of heat as waste. Is the amount of heat produced by a computer mining bitcoin the same as a traditional heater if they have the same input power? I know o...

Just like it says in the question title. I have heard that photons are force carriers of electromagnetism. Is it not true, that when a golf club imparts force on to a golf ball, then the fundamental force involved is the electromagnetic force ? Is yes, then would it be true , that during this int...
