The capacitors $C_1=71F,C_2=355F$ and $C_3=16\mathrm{.}5F$ are connected as shown below. What is the equivalent capacitance between points a and $b?$ Round all answers to $2$ significant figures.

If a $6$ V battery is connected across points a and $b,$ what is the charge in each capacitor?

The charge in $C_1,Q_1=q,C$

The charge in $C_2,Q_3=C$

The charge in $C_3,Q_3=C$
