In this introduction to capacitors tutorial, we will see that capacitors are passive electronic components consisting of two or more pieces of conducting material separated by an insulating material.
(Image source: Wikipedia) A capacitor consists of two metal plates that are separated by a dielectric material. When a voltage is applied to a capacitor, the electric charge accumulates on the plates. One plate of the capacitor collects a positive charge while the other collects a negative charge, creating an electrostatic field between them.
A basic unit consists of two conductors, or electrodes, separated from one another by an insulator, or dielectric. In order to easily collect electric charge, the electrode must be a good conductor of electricity. Materials widely used in capacitor manufacturing include aluminum, copper, nickel, palladium, platinum, silver, and tantalum.
It is the dominant characteristic that determines the capacitance value attainable at a given size and voltage. In other words, the higher the dielectric constant, the greater the capacitance for a particular capacitor design.
When a voltage V V is applied to the capacitor, it stores a charge Q Q, as shown. We can see how its capacitance may depend on A A and d d by considering characteristics of the Coulomb force. We know that force between the charges increases with charge values and decreases with the distance between them.
By applying a voltage to a capacitor and measuring the charge on the plates, the ratio of the charge Q to the voltage V will give the capacitance value of the capacitor and is therefore given as: C = Q/V this equation can also be re-arranged to give the familiar formula for the quantity of charge on the plates as: Q = C x V
