What is capacitor? Principle working, types and how it works

Case 1# The area of the plates parallel to each other. The capacitor has an area of plates very much. So it is the greater the capacitance. Case 2# If the distance between the plates is greater, it will reduce the capacitance. Case 3# Change the dielectric substance. It causes the capacitance to change, as well.

Charging and Discharging a Capacitor

Charging a Capacitor. Charging a capacitor isn''t much more difficult than discharging and the same principles still apply. The circuit consists of two batteries, a light bulb, and a capacitor. Essentially, the electron current from the batteries will continue to run until the circuit reaches equilibrium (the capacitor is "full").

Capacitor in Electronics

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
