Determine the current through the battery in the circuit shown in figure.

(a) immediately after the switch S is closed
(b) after a long time.

Text Solution

Verified by Experts

The correct Answer is:
A, C
a. Immediately after the switch is closed whole current passes through `C_1`.
`:. i=E/R_1`
b. Long after switch is closed no current will pass through `C_1 and C_2`.
`:. i=E/(R_1+R_3)`
