Calculate the energy stored in a capacitor of `6muF` when it is charged to a potential of 240 volt.

Energy stored in a capacitor and dissipated during charging a capacitor bear a ratio.

In which form is the energy stored in a charged capacitor?

Calculate the capacitance of a capacitor, required to share an energy of 10 kWh at a potential difference of 10^5V .

An air capacitor of capacity 50 mu F is charged to a potential of 200 V. The area of each plate is 20 cm^2 and the distance of separation between the plates is 0.1 mm, find the energy per unit volume of the electric field between the plates of the capacitor .

A capacitor has some dielectric between its plates and the capacitor is connected to a source. The battery is now disconnected and then the dielectric is removed. State whether the capacitance, the energy stored in it, the electric field, charges stored and voltage will increase, decrease or remain constant.

Calculate the heat generated in joule in a coil when potential difference of 30 volts is applied across it. The current of 0.8 A is passed for 4 minutes.
