## Homework Statement

S1 switch - always close.

S2 switch is closed, until the capacitor voltage reaches 2V.

given: R,C,V values.

V0 = 0V.

Need to find Vout while S1+S2 are closed and until S2 opens.

## Homework Equations

Vc(t) = (Vi - Vf)*(exp -t/TAU) + Vf

## The Attempt at a Solution

I have found the Vc(t) equation (until S2 opens) and got:

Vc(t) = 2/3V1*(1-exp(-3t/5RC))

but now i am alittle bit confused.

can't i tell that by KVL for the large loop (throught S2) each R has V1/3 voltage?

or i can't do it because we are in the charging stage?

thanks.
