Multiple-Choice Problem 3.

1. A.    The 10 µF and 20 µF capacitors have equal charges.
2. B.     The charge on the 20 µF capacitor is twice the charge on the 10 µF capacitor.
3. C.     The potential difference across the 10 µF capacitor is the same as the potential difference across the 20 µF capacitor.
4. D.    The equivalent capacitance of the network is 60 µF.
