Inductance

Inductance

​Key Terms and Definitions 

​Inductance (L)

​one property of a conductor that opposes change in current flow.

Counter Electromotive Force (cemf)

voltage developed in an inductive circuit by alternating current. The polarity of this voltage is, at every instant, opposite to that of the applied voltage.

Inductor

a conductor, usually a coil of wire, wound to concentrate its magnetic field, which produces a

predicted measure of inductance.

Henry (H)

unit of inductance. An inductance of one henry will produce one volt of cemf when ac current of one ampere at one hertz is applied.
