Question

State joules law of heating. Write in mathematical form

Answer 1

Answer:

The quantity of heat generated in a conductor when a current flows through it is

• directly proportional to the square of current for a given resistance and the time interval for which current flows.
• directly propotional to the resistance for a given current and time interval.
• directly propotional to the time for which current flows through the resistor for a given resistance and current , i.e. H = I^2Rt.

This mathematical equation is called Joule law of heating.
