Question

what causes the heat in this diagram?
resistance
voltage
amperage
electricity

Explanation:

When an electric current flows through a conductor, resistance causes some of the electrical energy to be converted into heat energy. This is known as Joule heating or resistive heating. Voltage is the potential difference that drives the current, amperage is the measure of the current itself, and electricity is the general form of energy. But it is the resistance of the material through which the current passes that directly causes the heat in such a scenario.

Answer:

Resistance
