What is Capacitation?

When does capacitation occurs? Define it.

The plates of a paraller-plate capacitor are made of circular discs of radii 5.0 cm each .If the separation between the plates is 1.0 mm,What is the capacitance?

Find the value of current( rms and peak) through a capacitor of 10 mu F when connected to a source of 110 V at 50 cycles supply. What is its capacitive reactance?

In a parallel plate capacitor, if the intervening medium of permittivity & between the plates is replaced by another medium of permittivity epsi/2 , then its capacitance is

A parallel plate capacitor consists of two identical circular plates of radius 3 cm which are separated by 2.5mm. Calulate the capacitance. What will be its capacitance if the separation is reduced to half the initial value?

A capacitor has capacitance C . Is this information sufficient to know what maximum charge the capacitor can contain? If yes, what is this charge? If no, what other information is needed?

The voltage between the plates of a parallel plate capacitor of capacitance 1.0 mu F is changing at the rate of 5 V s^(-1) . What is the displacement current in the capacitance ?
