Question

Two condensers of capacities $1\mu F$ and $2\mu F$ are connected in series and the system is charged to $120\mspace{6mu} volts$ . Then the P.D. on $1\mu F$ capacitor (in volts) will be

Answer 1

Solution

Charges developed are same so

$C_{1}V_{1} = C_{2}V_{2}$ ⇒ $\frac{V_{1}}{V_{2}} = 2$

$V_{1} + V_{2} = 120$ ⇒ $V_{1} = 80volts$
