Example 2:
Find the total capacitance and working voltage of two capacitors in series, when
both have a value of 150 µF, 120 V (Figure 16).

Total voltage that can be applied across a group of
capacitors in series is equal to the sum of the working
voltages of the individual capacitors.
working voltage = 120 V + 120 V = 240 volts
