## Homework Statement

I hope you can see the picture clearly. Someone drew lines over it,so please try to ignore that.

The problem here is to determine the current of ideal current source Ig, if following parameters are known:

-E1=50V, E3=30V

-R1=200Ω, R2=500Ω, R3=3kΩ, R4= 10 kΩ

-C=0.7 μF

-Charge flow trough the edge with capacitor after closing the switch Π is Q12 = 0.213 mC.

## Homework Equations

-Thevenin and Norton theorem.

-Ohm's law

-Millman's theorem

## The Attempt at a Solution

My attempt is to tranform the current generator to a voltage generator and then find the voltage U12. Then i would find Thevenin's generator and equivalent resistance and get a simple circuit. What to do after closing the switch. The biggest problem here is not exactly related to this problem -

**How does a voltage generator in an open edge affect the rest of the circut? Do we need to take it into calculations? How to set Kirchoff's second law equations? Are resistors in open edges included into calculating equivalent resistance for Thevenin's generator?**These problems arise because my base knowledge of circuits is weak. :L:L:L
