AB is a part of an electrical circuit (see figure). The potential difference " V _ A - V _ B ", at the instant when current i =2 ~A and is increasing at a rate of 1 amp / second is :

Options

  1. A5 volt
  2. B6 volt
  3. C9 volt
  4. D10 volt

Correct answer

D. 10 volt

Step-by-step solution

aligned & Apply K.V.L. & aligned & V _ A - LdI dt -5- IR = V _ B & ~V _ A - V _ B = LdI dt +5+ IR & =1 1+5+2 2 & =1+5+4 & =10 ~V aligned aligned
