I need to find the capacitance and inductance per unit length between 2 parallel wires. To do this, I have to calculate the E and B fields between the 2 wires, each with radius a, separated by d, where d is much bigger than a? Could you please show the whole derivation? (I assume you'd use Gauss' and Amperes' law but I could never get the proper value). Thanks.

Solution Summary

A line of two thin parallel wires sepearted by some distance is given.
1. The electric field and the capacitance is calculated when the two wires have electric charges on them.
2. The magnetic field and the inductance is calculated when the two wires carrying electric current through them.
