A branch of a circuit is shown in the figure. If current is decreasing at the rate of 10^3 As ⁻¹ , then the potential difference between A and B is
Options
- A1 V
- B5 V
- C10 V
- D2 V
Correct answer
A. 1 V
Step-by-step solution
aligned & Voltage of source, V =4 ~V & ~V _ L = L d l d t =9 10⁻³ 10^3 ~V =9 ~V & ~V _ AB - V _ R + V + V _ L =0 & or, V _ AB -14+4+9=0 & V _ AB -1=0 & V _ AB =1 ~V aligned
