A parallel plate capacitor with capacitance 1 F is being charged at a rate such that the potential difference across it changes at 10^6 V/s . The instantaneous displacement current between the plates is
Options
- A0 A
- B0.1 A
- C1 A
- D10⁻² A
Correct answer
C. 1 A
Step-by-step solution
The displacement current I_d between the plates of a capacitor is given by I_d = ₀ d _E dt Since the electric flux _E = EA = V d A , we have I_d = ₀ A d dV dt = C dV dt Given C = 1 F = 10⁻⁶ F and dV dt = 10^6 V/s I_d = 10⁻⁶ 10^6 = 1 A Answer: 1 A
