E&M

To find the inductance per unit length between the two conductors in a coaxial cable, we first use Ampere's law to find B (Magnetic field due to the inner conductor).

We then integrate along the volume of the cable. This gives us LI in which I is the current, and L is the inductance per unit length.

This class bores me....

Only 25 more minutes to go.....
