Physics Suppose voltage V is applied across a resistance R. The power dissipated in the resistance is P. Now the same voltage V is applied across a parallel combination of three equal resistors each of resistance R. Then the power dissipated in the second case will be 2p/ 3 3P P/3 P 2p/ 3 3P P/3 P ANSWER DOWNLOAD EXAMIANS APP
