A capacitor works in

By which type of supply capacitor works ?

Find the capacitance of a capacitor, if it is made up of 120 sheets of paraffined paper 0.1 mm thick, interspaced with aluminium foil sheets of 5 cm xx 3 cm dimensions. In what range of voltages can such a capacitor work?

A capacitor is filled with an insulator and a certain potential difference is applied to its pltaes. The energy stored in the capacitor is U . Now the capacitor is disconnected from the source and the insulator is pulled out of the capacitor. The work performed against the forces of electric field in pulling out the insulator is 4 U . Then dielectric constant of the insulator is.

A capacitor is connected to a battery. If we move its plates further apart, work will be done against the electrostatic attraction between the plates. What will happen to this work? What will be the effect on the energy of the capacitor?

A capacitor is getting charged by a battery of emf V what is the ratio of heat dissipated in the resistor to work done by battery when charge on capacitor is CV/2

If initial charge on all the capacitors were zero , work done by the battery in the circuit shown is
