The electric field lines are formed between the two plates, from the positive to the negative charges. The polarisation of the dielectric material by the electric field increases the capacitor''s surface charge proportionally to the electric field strength.
The ability of a capacitor to store energy in the form of an electric field (and consequently to oppose changes in voltage) is called capacitance. It is measured in the unit of the Farad (F). Capacitors used to be commonly known by another term: condenser (alternatively spelled "condensor").
(b) The dielectric reduces the electric field strength inside the capacitor, resulting in a smaller voltage between the plates for the same charge. The capacitor stores the same …
