A condenser of capacity $50\,\mu F$ is charged to $10\;volts$. Its energy is equal to
$2.5 \times {10^{ - 3}}\;joule$
$2.5 \times {10^{ - 4}}\;joule$
$5 \times {10^{ - 2}}\;joule$
$1.2 \times {10^{ - 8}}\;joule$
Two condensers of capacity $0.3\,\mu F$ and $0.6\,\mu F$ respectively are connected in series. The combination is connected across a potential of $6\,volts$. The ratio of energies stored by the condensers will be
As in figure shown, if a capacitor $C$ is charged by connecting it with resistance $R$, then energy is given by the battery will be
A $6\,\mu F$ capacitor is charged from $10\;volts$ to $20\;volts$. Increase in energy will be
Charge $'q'$ on a capacitor varies with voltage $'V'$ as shown. The area of $\Delta OPM$ represents
A parallel plate capacitor is charged to a certain potential and the charging battery is then disconnected. Now, if the plates of the capacitor are moved apart then:
