# Inductance

Written by Jerry Ratzlaff on . Posted in Electrical Engineering

Inductance, abbreviated as L, is the measure of an electric conductor or circuit by which an electromotive force is induced in it.

## Inductance FORMULA

 $$\large{ L = \mu \; n^2 \; \frac{A}{l} }$$

### Where:

 Units English Metric $$\large{ L }$$ = inductance $$\large{H}$$ $$\large{H}$$ $$\large{ A }$$ = area encircled by the coil $$\large{in^2}$$ $$\large{mm^2}$$ $$\large{ l }$$ = length of the coil $$\large{in}$$ $$\large{m}$$ $$\large{ n }$$ = number of turns of the coil $$\large{dimensionless}$$ $$\large{mu }$$  (Greek symbol mu) = permeability $$\large{ft^2}$$ $$\large{m^2}$$
