Problem

Three capacitors are connected in series across a

24\,\text{V}

source. Two of the capacitances are

2\,\mu\text{F}

and

6\,\mu\text{F}

; the third capacitor has an unknown capacitance

C_{x}

. A voltmeter reads

8\,\text{V}

across the unknown capacitor in steady state. What is

C_{x}

? a)

8\,\mu\text{F}

4\,\mu\text{F}

3\,\mu\text{F}

1\,\mu\text{F}
