## Homework Statement

Find I1,I2,I3,Uc

## Homework Equations

I was trying to make this task but my result was not correct

Before commutation

I=E/(R1+R2)=0.1 A

U=0.1*R2=100 V

After commutation

I=0 A

In the moment

equatations

I1*R1+I1*R2-I3*R2=E

I3*R2-I1*R2=Uc

I3=C*dUc/dt

But when I had got result

Uc=-200e^(-100t)+100

It was not correct.

## The Attempt at a Solution

R1=1000 Ohms

R2=1000 Ohms

C=20*10^-6 F

case 1

1)

E1=200 v

E2=0

case 2

2)

E1=200 V

E2=200 V

case 3

3)

E1=200sin(100t+45*)

E2=100

Are there any elements in the circuit after commutation?

Currents have Clockwise direction

There won't many changes in case 2.

But is there impendance in case 3?
