Capacitors in DC Circuits & RC

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:

Show answer and solution

Answer: (d)

At the instant of closing, the capacitor is uncharged and acts like a short wire.
A: false, current $\dfrac{5}{R}$ flows through $R$ . B: true, current is maximum at $t=0$ .
C: true, $V_{AB} = 0$ (minimum). D: true, charge is zero (minimum).
So the answer is (d) B, C, D only.
