Question

How does the amount of heat produced in a resistor depend upon current?

Answer 1

1. Whenever current flows in the circuit, resistance is offered to the flow of current in the circuit.
2. Due to this resistance, there will be heat produced in a conductor.
3. This heat produced by a resistor is given by, $H=i^{2}Rt$ and depends on three factors.

1. It is directly proportional to the square of the current ($i$).
2. It is directly proportional to the resistance of the conductor ($R$).
3. It is directly proportional to the time for which the current flows ($t$).
