1. The problem statement, all variables and given/known data 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. 2. Relevant equations Vc(t) = (Vi - Vf)*(exp -t/TAU) + Vf 3. 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.
