How a two wire conductor has capacitance?

A two-wire conductor has capacitance due to the electric field that forms between the two wires when a voltage is applied across them. This electric field allows the wires to store electrical energy, effectively acting as a capacitor. The capacitance depends on factors such as the distance between the wires, their lengths, and the dielectric properties of the surrounding medium. Thus, even without a dielectric material, the two-wire arrangement inherently possesses capacitance.
