Question

What is the equivalent capacitance between points A and B?

• A. $1\mu F$
• B. $2\mu F$
• C. $3\mu F$
• D. $6\mu F$

Answer 1

The correct option is A $1\mu F$

This is a series combination of capacitors.
We can calculate the equivalent capacitance as
$\frac{1}{C}=\frac{1}{C_1}+\frac{1}{C_2}+\frac{1}{C_3}+.....$
Here,
$\frac{1}{C}=\frac{1}{2}+\frac{1}{3}+\frac{1}{6}$
$\frac{1}{C}=\frac{1}{1}$
$C=1\mu F$
