Answer:

The equivalent capacitance of the series combination of capacitors is 2\mu F.

Explanation:

Given three capacitors connected in series.

The capacitances of capacitors are C_{1} =4 \mu F, C_{2} = 6 \mu F and C_{3} = 12 \mu F

When two capacitors, C_{1} and C_{2} are connected in series, then the equivalent capacitance of the combination of capacitors is given by

\frac{1}{C} =\frac{1}{C_{1}}+ \frac{1}{C_{2}}.

Thus, the equivalent capacitance of the given capacitors in series is

\frac{1}{C} =\frac{1}{C_{1}}+ \frac{1}{C_{2}}+ \frac{1}{C_{3}}

=\frac{1}{4}+ \frac{1}{6}+ \frac{1}{12}

= \frac{3+2+1}{12}

= \frac{6}{12}= \frac{1}{2}

Since \frac{1}{C} =\frac{1}{2}, therefore C=2\mu F

Hence, the equivalent capacitance of the series combination of capacitors is 2\mu F.
