A part of a complete circuit is shown in the figure. At some instant, the value of current I is 1 A and it is decreasing at a rate of 10 2 As - 1 . The value of the potential difference V p - V Q , (in volts) at that instant is-

Correct answer

0

Step-by-step solution

V p - L d l d t - 30 + R I = V Q V P - V a = + 50 × 10 - 3 × 10 2 + 30 - 1 × 2 =   +   5   +   30   –   2   =   33
