Inductance of Transmission Line

Inductance is an electrical term related to conductor or inductor. Inductance is the property or capability of a conductor to oppose the change of flow of current through a particular circuit. The term inductance is from the inductor. The symbol L denotes inductance, and the unit of inductance is Henry (H). Inductance is generally a ratio of voltage and rate of change in current (Ampere). In practice, every conductor has an inductance property.
