Question 380: Electrostats & Capacitance

Question

In the given circuit, $$\mathrm{C}_{1}=2 \mu \mathrm{F}, \mathrm{C}_{2}=0.2 \mu \mathrm{F}, \mathrm{C}_{3}=2 \mu \mathrm{F}, \mathrm{C}_{4}=4 \mu \mathrm{F}, \mathrm{C}_{5}=2 \mu \mathrm{F}, \mathrm{C}_{6}=2 \mu \mathrm{F}$$, The charge stored on capacitor $$\mathrm{C}_{4}$$ is ____________ $$\mu \mathrm{C}$$.

Accepted Answer

$$
\begin{aligned}
& \mathrm{C}_{\mathrm{eq}}=0.5 \mu \mathrm{F} \\
& \mathrm{Q}=0.5 	imes 10=5 \mu \mathrm{C} \\
& \mathrm{Q}^{\prime}=\frac{5 \mu \mathrm{C} 	imes 0.8}{0.8+0.2}=4 \mu \mathrm{C}
\end{aligned}
