When a "hot" wire and a "neutral" wire actually touch each other and a large amount of current flows;
and when electricity traveling from the source, to the load on the hot wire and returning to the source.

Measure of the flow of electrons in a circuit (how much power do you get) and how well a material or object conducts electricity.
What is current and resistance?
500
Heat can be transferred from one object to another; the transfer of heat through waves of electromagnet; can be either natural, where heat rises on its own, or forced, where you control the movement of the heat.
