The correct Answer is:
To solve the problem, we need to find both the conduction current through the connecting wires and the displacement current through the plates of the capacitor. ### Step-by-Step Solution: 1. **Identify the given values:** - Capacitance of the capacitor, \( C = 20 \, \mu F = 20 \times 10^{-6} \, F \) - Rate of change of voltage, \( \frac{dV}{dt} = 3 \, V/s \) 2. **Use the formula for displacement current:** The displacement current \( I_d \) through a capacitor can be calculated using the formula: \[ I_d = C \frac{dV}{dt} \] 3. **Substituting the values into the formula:** \[ I_d = 20 \times 10^{-6} \, F \times 3 \, V/s \] 4. **Calculate the displacement current:** \[ I_d = 60 \times 10^{-6} \, A = 60 \, \mu A \] 5. **Conduction current:** In a charging capacitor, the conduction current \( I_c \) is equal to the displacement current \( I_d \) when the capacitor is charging. Therefore: \[ I_c = I_d = 60 \, \mu A \] ### Final Answer: - The conduction current through the connecting wires is \( 60 \, \mu A \). - The displacement current through the plates of the capacitor is also \( 60 \, \mu A \).
