Capacitors in Series: Unknown Capacitance

APPHEM-6YVAQK

Two capacitors, $C_1$ and $C_2$, are connected in series with a 12.0-volt direct-current source. The capacitance of $C_1$ is $600 \mu F$. When a voltmeter is connected across $C_1$, the voltmeter reads 3.0 volts.

What is the capacitance of $C_2$?

A

$200 \mu F$

B

$300 \mu F$

C

$600 \mu F$

D

$900 \mu F$

E

$1,800 \mu F$
