Assertion : The switch `S` shown in the figure is closed at `t = 0`. Initial current flowing through battery is `(E)/(R + r)` Reason : Initially capacitor was uncharged, so resistance offered by capacitor at `t = 0` is zero A. Statement I is true, Statement II is True, Statement II is a correct explanation for Statement I.B. Statement I is True, Statement II is True, Statement II is not a correct explanation for Statement I.C. Statement I is True, Statement II is False.D. Statement I is False, Statement II is True. |

Answer» Correct Answer - A a. Charge on capacitor `q = CE(1-e^(-t//CR_(eq)))` `:. I = (dq)/(dt) = E/R_(eq) e^(-t//CR)` at `t = 0 , I = E/R_(eq) = E/R+r` Therefore, resistance offered by the capacitor is zero. |
