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 P 2p/ 3 P/3 3P P 2p/ 3 P/3 3P ANSWER DOWNLOAD EXAMIANS APP
Physics Why two thin shirts can keep us warmer than a single thick shirt in winter ? Air layer between two shirts behaves like insulating media Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts works as good conductor No radiation of heat takes place Air layer between two shirts behaves like insulating media Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts works as good conductor No radiation of heat takes place ANSWER DOWNLOAD EXAMIANS APP
