Question

What is an example of a combination of capacitors practice problem?

Answer 1

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`*

This is just one example—capacitor problems can easily become more complicated.
