Capacitance of a Pair of parallel identical wires

Description

Capacitance is the ability of a body to store an electrical charge. Any object that can be electrically charged exhibits capacitance. The capacitance is a function only of the geometry (including their distance) of the conductors and the permittivity of the dielectric. It is independent of the potential difference between the conductors and the total charge on them.
The capacitance of a pair of parallel identical wires is depended on the wire’s radius, their length and the distance between them.
