Assertion : The switch S shown in the fi...

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.

Text Solution

Verified by Experts

The correct Answer is:
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.
