## Homework Statement

The switch S is closed for a long time and the current flowing is constant.

Given that C1 = 3 μF, C2 = 6 μF, R1 = 4 kΩ, R2 = 7 kΩ

If the power at R2 resistor is 2,4 W

a) Determine the charge at C1

b) When the switch is opened, after some miliseconds, how much does charge at C2 change?

## Homework Equations

KVL, KCL

## The Attempt at a Solution

I still have no idea whether the current at right loop is zero when the switch is opened. Please help..
