Question

The equivalent capacitance between the points A and B in the given diagram is:

• A. $8\mu F$
• B. $6\mu F$
• C. $\frac{8}{3}\mu F$
• D. $\frac{3}{8}\mu F$

Answer 1

The correct option is C $\frac{8}{3}\mu F$

$C_S$ Capacitance in series

$\begin{array}{c}\frac{1}{C_S}=\frac{1}{2}+\frac{1}{2}+\frac{1}{2}\\ =\frac{3}{2}\\ C_S=\frac{2}{3}\end{array}$

The equivalent capacitance between A & B is

$\begin{array}{c}{C}_P=\frac{2}{3}+2\\ C_P=\frac{8}{3}\mu F\end{array}$
