# Inductance

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

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