A capacitor is charged by using a battery which is then disconnected. A dielectric slab is then slipped between the plates which results in

The energy stored in a capacitor is in the form of

Two capacitors $2 \mathrm{\mu F}$ and $4 \mathrm{\mu F}$ are connected in parallel. A third capacitor of $6 \mathrm{\mu F}$ capacity is connected in series. The combination is connected across a $12 \mathrm{V}$ battery. The voltage across a $2 \mathrm{\mu F}$ capacitor is:

In the given circuit, if point $b$ is connected to earth and a potential of $1200 \mathrm{V}$ is given to a point $a,$ the charge on $4 \mathrm{\mu F}$ capacitor is

A circuit is shown in the given figure. Find out the charge on the condenser having capacity $5 \mathrm{\mu F}$.
