Answer:

Dielectrics:

they are insulating materials

they transmit electric effects without conducting

they are of two types

  • Non polar dielectrics
  • polar dielectrics

Capacitance:

the ratio between the charge on either of the conductors and potential difference between them

it is measured in Farad(F)

DIELECTRICS

dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material.

CAPACITANCE

Capacitance is the ratio of the change in electric charge of a system to the corresponding change in its electric potential.

CAPACITORS

A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. ... While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit.
