Question

State joule's heating effect of current

Answer 1

According to the Joule's heating effect of current, when current I flows through a resistor of electric resistance R, heat is produced. The amount of heat produced is directly proportional to the:

(i) the square of current flowing in a circuit

(ii) resistance in the circuit and

(iii) time in which the current flows in the circuit

i.e H=I${}^2$Rt
