Question

How will the heat produced in a conductor change in each of the following cases?
(i) The current flowing through the conductor is doubled.
(ii) Voltage across the conductor is doubled.
(iii) Time for which current passed is doubled.

Answer 1

Answer:

Electric current in the conductor is due to flow of electrons. When these flowing electrons bump into atoms in the conductor, they transfer some of their kinetic energy to them. This produces heat in the conductor and increases its temperature. ... Because of resistance, specifically to the glow of electricity
