Vedclass · Answer

(A) According to Joule's law of heating,the heat $(H)$ produced in a conductor is given by the formula $H = I^2Rt$,where $I$ is the current,$R$ is the resistance,and $t$ is the time for which the current flows.From this relation,it is clear that $H \propto R$ when $I$ and $t$ are constant.Therefore,the heat dissipated is directly proportional to the resistance of the conductor.

Heat dissipated by a conductor when a current is passed through it is directly proportional to the resistance of the conductor.
