1. The problem statement
The capacitors in the figure are initially uncharged and are connected, as in the diagram, with switch S open. The applied potential difference is Vab = + 210 V.
What is the potential difference Vcd?
(series) 1/C = 1/c1 + 1/c2 + ...
(parallel) C = c1 + c2 + ...
C=Q/V
Trying to find Vcd:
I first found the equivalent capacitance of the series, which is 4*10-6 F. I calculated the charge on the capacitors using Q = CV, which was 8.4*10-4. Then, I tried to find Vad and Vac by using V=Q/C. I don't think this is the right way to do this problem though.
