Charge $'q'$ on a capacitor varies with voltage $'V'$ as shown. The area of $\Delta OPM$ represents
capacitance
capacitive reactance
magnetic field between the plates
energy stored in the capacitor
The insulated spheres of radii ${R_1}$ and ${R_2}$ having charges ${Q_1}$and ${Q_2}$ respectively are connected to each other. There is
The energy density $u$ is plotted against the distance $r$ from the centre of a spherical charge distribution on a $log$-$log$ scale. The slope of obtianed straight line is :
The capacity of a condenser is $4 \times {10^{ - 6}}$ farad and its potential is $100\,\,volts$. The energy released on discharging it fully will be.......$Joule$
A condenser of capacity $50\,\mu F$ is charged to $10\;volts$. Its energy is equal to
A capacitor is charged to $200\, volt$ it has $0.1$ coulomb charge. When it is discharged, energy will be.....$J$
