$$
\text { Find the equivalent capacitance between a, b. }
$$

$$
C_{eq}=\frac{c_{1} c_{2}}{c_{1}+c_{2}}=\frac{98*16}{98+16}=12 \mu F
$$

$$
C_{eq}=C_{1}+C_{2}=12+3=15 \mu  F
$$

$$
C_{eq}=\frac{C_{1} C_{2}}{C_{1}+C_{2}}=\frac{15 * 30}{15+30}=10 \mathrm{\mu F}
$$

$$
C_{eq}=C_{1}+C_{2}=10+10=20 \mu F
$$

$$
\frac{1}{c_{eq}}=\frac{1}{c_{1}}+\frac{1}{c_{2}}+\frac{1}{c_{3}}
$$

$$
\frac{1}{c_{eq}}=\frac{1}{20}+\frac{1}{4}+\frac{1}{5}
$$

$$
c_{eq}=2 \mu  F
$$
