A `800 muF` capacitor is charged by a 100V battery. After some time, the battery is disconnected. The capacitor is then connected to another `800muF` capacitor. What is the electrostatic energy stored ?

A 500 pF capacitor is charged by a 100V supply. It is then disconnected from the supply and is connected to another uncharged 500pF capacitor. How much electrostatic energy is lost in the process?

A 600 pF capacitor is charged by a 200 V supply. It is then disconnected from the supply and is connected to another uncharged 600 pF capacitor. How much electrostatic energy is lost in the process ?

A 6muF capacitor is charged by a 300 V supply. It is then disconnected from the supply and is connected to another uncharged 3muF capacitor. How much electrostatic energy of the first capacitor is lost in the form of heat and electrostatic radiation?

A 12 pF capacitor is connected to a 50 V battery. How much electrostatic energy is stored in the capacitor ?

A 10 muF capacitor is charged to a 25 volt of potential.The battery is disconnected and a pure 100 mH coil is connected across the capacitor so that LC oscillations are set up. Calculate the maximum current in the coil.

If the plates of a charged capacitor are suddenly connected to each other by a wire, what will happen?

A 16 μF capacitor is charged to a 20 volt potential. The battery is then disconnected and a pure 40 mH coil is connected across the capacitor so that LC oscillations are set up. The maximum current in the coil is :

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.
