1. The problem statement, all variables and given/known data All capacitors of the open circuit (figure below) are discharged when, at t=0, the switch S1 is closed. At some point later, t= t1, the switch S2 is then closed. What is the charge Q1( t2) on the capacitor C1 at time t= t2 > t1? 2. Relevant equations C = Q / V ... Q = C * V Ceq = (1/C1) + (1/C2) 3. The attempt at a solution I need some help getting started. Having no numbers is throwing me off and i don't quite understand.
