Question

Find the charges on the three capacitors connected to a battery as shown in figure (31-E1). Take $C_1=2.0\mu F,C_2=4.0\mu F,C_3=6.0\mu F$ and $V=12$ volts.

Answer 1

$C_1=2\mu F,C_2=4\mu F,$

$C3=6\mu F,V=12V$

$C_{eq}=C_1+C_2+C_3$

$=2+4+6$

$=12\mu F=12\times {10}^{-6}F$

$q_1=12\times 2=24\mu C,$

$q_2=12\times 4=48\mu C,$

$q_3=12\times 6=72\mu C$
