In the circuit shown below, the switch S is connected to position P for a long time so that the charge on the capacitor becomes C. Then S is switched to position Q. After a long time, the charge on the capacitor is C.

The magnitude of is ____.

Answer: 0.67

Solution

When switch is at position Q, in steady state:

Applying KVL: , giving , so A.

Potential difference: V.

Charge on capacitor: μC.
