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-1 is True,Statement-2 is True, Statement-2 is a correct explanation for Statement-1B. Statement-1 is True,Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1C. Statement -1 is True, Statement-2 is false.D. Statement-1 is False, Statement-2 is True. |
Answer» Correct Answer - 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)implies` resistance offered by capacitor is zero, |
