You can convert the electricity to heat but the electrons themselves are not heat. You must go again to school and learn the real physics.
"I believe that all mathematical physicists should be hanged
from the highest trees and telephone poles available.
If the laws forbid this, or it messes up the landscape,
then we should institutionalize the whole lot of them.
But keep in mind that there aren't enough funny farms to hold so many idiots.
I'm so upset that relativists hold the reins of power that I think that I'll
just go and read the newspaper to cool off..."

http://www.youstupidrelativist.com/You mean the mathematical physics that make possible the device you are using to spout nonsense? I understand the math that makes the pnp, or npn junctions possible in your cpu, but this math is wrong?

You can't convert things to heat, heat is a process not a state. You don't increase the heat of something, this is non-sensical, literally it doesn't make sense. You can increase the kinetic energy of the particles, or the potential energy of the electrons through a process called heating.
Compressing a gas increases its temperature, you haven't heated it, why?
Transferring a fluid from one area to another doesn't create fluid, it simple moves it.
Heat is the transfer of energy, it is not energy. The energy itself is thermal energy, which in part is the quantum energy levels of the bound electrons. At absolute zero, the electrons collapse to the lowest energy levels and fill their shells. You are confused, uneducated and wrong.
I have an MSc in applied physics with emphasis in solid state.
You?
