The circuit is in a steady state.

The charge in capacitor `C_2` is

Options

A. `30muC`
B. `10 muC`
C. `20 muC`
D. `40 muC`

Answer

C

Explanation

c. At steady state, the circuit will be simplified to the following circuit :

Using Kirchhoff's law, we can
calculate `I = 1A` .
Further using Kirchhoff's law in
original circuit, we can calculate
charges on different capacitors.
