Question

Find out the effective capacitance between points A and B as shown in the figure. Here ${C_1 = C_2 = 20 \, \mu F }$ and ${C_3 = C_4 = 10 \, \mu F}$

• A. ${10 \, \mu F}$
• B. ${15 \, \mu F}$
• C. ${20 \, \mu F}$
• D. ${25 \, \mu F}$

Answer 1

Answer: (B)

${15 \, \mu F}$

Answer 2

Here, $C_1$ and $C_2$ are in series. Hence, their effective capacitance $C'$ is given by
