Answer:

See below.

Explanation:

Here is a fairly typical example I grabbed from an old discussion problems packet from a general physics class (collegiate-level, General Physics II)

Two capacitors, one with #C_1=6.0muF# and the other with #C_2=3.0muF#, are connected to a potential difference of #18V#

a) Find the equivalent capacitances when they are connected in series and in parallel

answer: #2.0muF# in series and #9.0muF# in parallel

b) Find the charge and potential difference for each capacitor when they are connected in series

answer: #Q_1=36muC#, #Q_2=36muC#, #V_1=6V#, and #V_2=12V#

c) Find the charge and potential difference for each capacitor when they are connected in parallel

answer: #Q_1=108muC#, #Q_2=54muC#, #V_1=18V#, and #V_2=18V#*

Capacitor problems can easily become more complicated.
