Two long straight wires with equal cross-sectional radii a are located parallel to each other in air. The distance between their axes equals b. Find the mutual capacitance of the wires per unit length under the condition b >> a.
Let us suppose that linear charge density of the wires be λ then, the potential difference, The intensity of the electric field created by one of the wires at a distance x from its axis can be easily found with the help of the Gauss’* theorem,
