JEE Advanced2021PhysicsCapacitanceActual
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 q₁ C . Then S is switched to position Q . After a long time, the charge on the capacitor is q₂ C . The magnitude of q 1 is _______.
Correct answer
0
Step-by-step solution
When S is connected to P , In steady state, i = 2 − 1 2 + 1 ⇒ i = 1 3   A Now, Charge on capacitor, q = C V ⇒ q = 1 μF 4 3   V ⇒ q = 4 3 μC ⇒ q = 1.33   μC
