A switch is connected in between a 12 V battery and an uncharged capacitor and a 1 k$\Omega$ resistor. At the time instant when the switch is closed, the voltage across the capacitor is
- A. 6 V
- B. 12 V
- C. 0 V
- D. 24 V
Answer: C. 0 V
Explanation: A capacitor doesn't allow a sudden change in voltage. Voltage (just before switching) = Voltage (just after switching) = 0 V.
