In the circuit shown in figure, the capacitor is initially uncharged. At t = 0, the switch is closed at position (1) and remain closed for long time. Then at t =t', switch is shifted to position (2).
Column-I | Column-II |
(i) As the capacitor charges from t = 0 to t = t' | [A] Current in the circuit falls exponentially |
(ii) As the capacitor discharge i.e. for t > t' | [B] Current in the circuit grows exponentially |
(iii) Maximum current in the circuit depends on | [C] R, C |
(iv) Time to achieve 50% charging of the capacitor depends on | [D] R |
