Question 110: Electrostatics & Capacitance

Question

In the given figure the total charge stored in the combination of capacitors is $100~ \mu \mathrm{C}$. The value of ' $x$ ' is _________.

Accepted Answer

Charge on $\mathrm{C}_1$ is $\mathrm{Q}_1=2 	imes 10=20 \mu \mathrm{C}$ .....(i)
Charge on $\mathrm{C}_2$ is $\mathrm{Q}_2=\mathrm{x} 	imes 10=10 \mathrm{x} \mu \mathrm{C}$ .....(ii)
Charge on $\mathrm{C}_3$ is $\mathrm{Q}_3=3 	imes 10=30 \mu \mathrm{C}$ .....(iii)
Total charge $20+10 \mathrm{x}+30=100$ $\Rightarrow x=5$
