NEET2019PhysicsCapacitanceActual
A parallel plate capacitor of capacitance 20  μ F is being charged by a voltage source whose potential is changing at the rate of 3   V   s - 1 . The conduction current through the connecting wires, and the displacement current through the plates of the capacitor would be, respectively:
Options
- Azero ,   60   μ A
- B60   μ A ,   60   μ A
- C60   μ A , zero
- Dzero, zero
Correct answer
B. 60   μ A ,   60   μ A
Step-by-step solution
q = C V d q d t = C d v d t = 20 × 10 - 6 × 3 Conduction current = 60   μA Displacement current = ε 0 d ϕ e d t = ε 0 A d dV d t = 60   μA
