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 3P P P/3 2p/ 3 3P P P/3 2p/ 3 ANSWER DOWNLOAD EXAMIANS APP
Physics Why are we able to hear short wave broadcasts better than long wave broadcasts ? Short wave broadcasts are made by nearby radio stations. By convention, short waves are meant for long distances, whereas long waves are reserved for short distances. Short waves are more energetic than long waves. Short waves are unaffected by atmospheric disturbances. Short wave broadcasts are made by nearby radio stations.
