The capacitance of a parallel plate condenser does not depend on

Between the plates of a parallel plate condenser there is 1mm thick paper of dielectric constant 4. It is charged at 100 volt. The electric field in volt/metre between the plates of the capacitor is

The electric field between the two spheres of a charged spherical condenser

The distance between the plates of a parallel plates capacitor is d. A metal plate of thickness d / 2 is placed between the plates. The capacitance would then be

An uncharged capacitor is connected to a battery. On charging the capacitor

A capacitor is kept connected to the battery and a dielectric slab is inserted between the plates. During this process

The capacitance of an air capacitor is 15µF the separation between the parallel plate is 6 mm. A copper plate of 3 mm thickness is introduced symmetrically between the plates. The capacitance now becomes

An air capacitor is connected to a battery. The effect of filling the space between the plates with a dielectric is to increase

A light bulb, a capacitor and a battery are connected together as shown here, with switch S initially open, When the switch S is closed, which one of the following is true

The diameter of each plate of an air capacitor is 4 cm. To make the capacity of this plate capacitor equal to that of 20 cm diameter sphere, the distance between the plates will be
