Question

What is the effective capacity between points A and B of the network of capacitors shown in figure?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

Answer: (C)

$\frac{1}{c}=\frac{1}{3}+\frac{1}{6}$ $\frac{1}{c_2}=\frac{1}{2}+\frac{1}{2}$

$\frac{1}{c_1}=\frac{3}{6}$ $c_2=1\mu F$

$c_1=2\mu F$

Both are parallel and when capacitor were parallel

$c_{eq}=c_1+c_2$

$=2+1$

$3$.
