Physics A wire of copper having length I and area of cross-section A is taken and a current i is flown through it. The power dissipated in the wire is P. If we take an aluminium wire having same dimensions and pass the same current through it, the power dissipated will be P > P 2P < P P > P 2P < P ANSWER DOWNLOAD EXAMIANS APP
