Vedclass · Answer

(A) The heat produced per unit time in a conductor is defined as the electric power $P$ dissipated in the conductor.According to Joule's law of heating,the power dissipated is given by the formula:$P = I^2 R$where $I$ is the electric current and $R$ is the resistance of the conductor.Since the temperature is constant,the resistance $R$ remains constant.Therefore,the heat produced per unit time is directly proportional to the square of the electric current $(P \propto I^2)$.Thus,the correct option is $A$.
