Explanation:
Let the current flowing through the resistor be I and potential difference across its ends be V. In time t, let Q amount of charge flows through the resistor. ... Heat produced, H=W=V x I x t => VIt. H= VIt.

Answer:
When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors:
- The resistance, R of the conductor.
- A higher resistance produces more heat.
- The time, t for which current flows.
- The longer the time the larger the amount of heat produced amount of current, I.
- the higher the current the larger the amount of heat generated.
Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called Joule’s equation of electrical heating.
