An alternating voltage of amplitude 40 ~V and frequency 4 kHz is applied directly across the capacitor of 12 F . The maximum displacement current between the plates of the capacitor is nearly :
Options
- A10 ~A
- B12 ~A
- C8 ~A
- D13 ~A
Correct answer
B. 12 ~A
Step-by-step solution
Displacement current is same as conduction current in capacitor. aligned & X_C= 1 C = 1 2 fC & = 1 2 4 10^3 12 10⁻⁶ =3.317 aligned I= V X_C = 40 3.317 =12 ~A
