Question

A current source drives a current in a coil of resistance R₁ for a time t. The same source drives current in another coil of resistance R₂ for same time. If heat generated is same, find internal resistance of source.(a) $\frac{R_{1}R_{2}}{R_{1}+R_{2}}$(b) R₁ + R₂(c) zero(d) $\sqrt{R_{1}R_{2}}{$
