Fill ups
A capacitor is a ………………..for d.c.

Fill ups: The basic use of a capacitor is to ………………….charge and energy.

What do you mean by inductive reactance, capacitive reactance and impedance? Show that a capacitor is a block for d.c., and an inductor, a block for a.c.

How does capacitor behave to d.c.?

Fill ups: A dielectric is used in a capacitor to ………………….its capacitance.

How does capacitive reactance X_c of a capacitor vary in an a.c. and d.c. circuit ?

When an ideal capacitor is charged by a d.c. battery,no current flows.However,when an a.c. source is used,the current flows continously.How does one exlain this,based on the concept of displacement current.

Show that a capacitor is an easy path for a.c. but a block for d.c. (i.e. offers infinite resistance for d.c.).

A parallel plate capacitor is charged to a potential difference V by a d.c. source. The capacitor is then disconnected from the source. If the distance between the plates is doubled, state with reason how the following will change. energy stored in the capacitor.

A parallel plate capacitor is charged to a potential difference V by a d.c. source. The capacitor is then disconnected from the source. If the distance between the plates is doubled, state with reason how the following will change. electric field between the plates
