Q:

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

A) P B) 3P
C) p/3 D) 2p/ 3
 
Answer & Explanation Answer: B) 3P
