One coulomb of charge is equal to 6,250,000,000,000,000,000 electrons.
Meaning there are 6,250,000,000,000,000,000 free electrons in wire?

What really is free electron? An electron that is not attach in any atom?

What is an atom? I understand it is the smallest unit of matter, so what is it?

What is the difference between
horsepower and torque?



What really is voltage. i understand it is a potentional force or push and it pushes the current. So why is it push? Is it because of the attraction analogous to gravity?


why every thing has resistance (exc. superconductivity )


thnx

You can't put 5 questions in one post and expect good answers, especially when some of the answers would need a whole book to explain them.
