Ok try to review for the finals but I need help in understanding this problem.
So I can say that there is a resistance, 2 capacitors in series, and voltage source (Vo).
Vo = 20.0 V
R = 5.00 kilo ohm
C1 = 12.0 micro F
C2 = 4.0 micro F
Switch is closed at t = 0.
How much energy will be store in C1 20.0 ms after the switched closed.
U = Q^2/2C = 1/2CV^2 = 1/2 QV
V(t) =Vo(1-e^(-taw/RC)
V(t) = 20V(1-e^-(20.0E-3 s/(5.00E3 ohms)(is this C the Ceq for the Capacitors because I only wrote C1 and I got it wrong)
V(t) = ______ volts
U = 1/2 _____volts x ______Faradays = _______ J
