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 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").

Working Principle of a Capacitor. As we know that when a voltage source is connected to conductor it gets charged say by a value Q. And since the charge is proportional to the voltage applied, we can say that: Q∝V. In order to equate the charge Q and voltage V.

An electrolytic capacitor is a capacitor that to produce a higher capacitance than other capacitor types employs an electrolyte. A liquid or gel that has a lot of ions in it is an electrolyte. Since almost all electrolytic capacitors are polarised, the positive terminal''s voltage must always be higher than the negative terminal''s voltage. Large […]
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. Initially

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.
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.
