Identify the valid statements relevant to the given circuit at the instant when the key is closed. A. There will be no current through resistor R. B. There will be maximum current in the connecting wires. C. Potential difference between the capacitor plates A and B is minimum. D. Charge on the capacitor plates is minimum.
Choose the correct answer from the options given below:
(A)C, D only
(B)B, C, D only✓ Correct
(C)A, C only
(D)A, B, D only
Answer: (B)
Solution
At the instant the key is closed, the capacitor is uncharged, so it behaves like a short circuit — zero potential difference across its plates and zero charge on them. Because the capacitor offers no resistance to current flow at this instant, the current in the connecting wires is at its maximum possible value.
So the charge on the capacitor plates is minimum, the potential difference across plates A and B is minimum, and the current in the connecting wires is maximum.
