Capacitance is the ability of a material or device to store electric charge, and is measured by the ratio of charge to electric potential. It can also be defined as the change in an electric charge of material to the corresponding change in the electric potential.    Capacitance is important because it results from a body coming into contact with an electric charge and a load that results in a closed circuit. For example, the charges carrying current in conductors make capacitance between each other as well as other nearby objects.   Capacitance can be determined experimentally using... Show more

Capacitance is the ability of a material or device to store electric charge, and is measured by the ratio of charge to electric potential. It can also be defined as the change in an electric charge of material to the corresponding change in the electric potential.   

Capacitance is important because it results from a body coming into contact with an electric charge and a load that results in a closed circuit. For example, the charges carrying current in conductors make capacitance between each other as well as other nearby objects.
 
Capacitance can be determined experimentally using linear extrapolations of titration data, or measured using a capacitance-voltage (C--V) measurement. 
The capacitance formula is \(q=CV\), where \(q\) = charge, \(C\) = capacitance, and \(V\) = voltage. 

Capacitance increases with conductor area, so that surface area of the conductor, and therefore the size of a pipe, affects the distance the signal will carry. For example, the same signal strength will leak away over a much shorter distance from a large pipe than from a small one. 

Capacitors are energy-storing devices available in many sizes and shapes.
