हिन्दीA parallel plate capacitor of capacitance \( 20\text{ }\mu\text{F} \) is being charged by a voltage source whose potential is changing at the rate of \( 3\text{ V/s} \). The conduction current through the connecting wires, and the displacement current through the plates of the capacitor, would be, respectively:
Correct answer · Option 4
\( 60\text{ }\mu\text{A}, 60\text{ }\mu\text{A} \)
Explanation
Conduction current \( I_c = C\frac{dV}{dt} = 20\text{ }\mu\text{F} \times 3\text{ V/s} = 60\text{ }\mu\text{A} \). Displacement current equals conduction current in continuity, so \( I_d = I_c = 60\text{ }\mu\text{A} \).
