Q. Four capacitor of equal capacitance have an equivalent capacitance $C_{1}$ when connected in series and an equivalent capacitance $C_{2}$ when connected in parallel. The ratio $C_{1}/C_{2}$ is
A) $1/4$
B) $1/16$
C) $1/8$
D) $1/12$
Explanation
(b) $C_{1} = \frac{C}{4}$ (series); $C_{2} = 4C$ (parallel)
$\therefore\frac{C_{1}}{C_{2}} = \frac{C/4}{4C} = \frac{1}{16}$
