C1 = C2 = C3 = C4 = C
Determine the charge on each capacitor in terms of C and V.
Determine the potential difference across each in terms of V.
Q = CV
Charged is conserved across capacitors in series and divided across parallel.
Voltage is conserved across capacitors in parallel and divided across series.
The Attempt at a Solution
All I've been able to figure out is the total capacitance
Cba = 3/5 C
