Question

Heating effect of current is due to

• A. the flow of voltage through the conductor.
• B. the flow of current through a conductor.
• C. both A and B.
• D. neither A nor B.

Answer 1

The correct option is B the flow of current through a conductor.

Whenever an electric current passes through a conductor, it gets heated up. The amount of heat produced is directly proportional to the square of the current ($H\propto i^2$).
