Question

The two capacitors $2\mu F$ and $6\mu F$ are put in series, the effective capacity of the system in $\mu F$ is:

• A. $8$
• B. $2$
• C. $\frac{3}{2}$
• D. $\frac{2}{3}$

Answer 1

The correct option is C $\frac{3}{2}$

$2\mu F,6\mu F$ are in series

$C_{eq}=\frac{C_1{C}_2}{C_1+C_2}$

$=\frac{2\times 6}{(2+6)}=\frac{12}{8}=\frac{3}{2}\mu F$
