Let’s start by reviewing the concept of inductance.

## Inductance

**Inductance** of a conductor is the property that a change in current in a conductor causes a electro motive force (emf or voltage) to be induced in a conductor.

We can speak of **self inductance** where the voltage is induced in the same conductor as the changing current, or **mutual inductance** where the changing current in one conductor induces a voltage in another conductor. Continue reading The private and public scope of coaxial cable
