August 12 Fact-of-the-Day

Self-inductance is a property of electrical circuits that causes them to oppose a change in current flowing through them. The opposition manifests as back electromotive force (voltage) that develops when current intensity changes. A circuit has an inductance of one henry (the practical unit of inductance) if it develops a back electromotive force of one volt when current through it changes at a rate of one ampere-per-second. ©2004 Martek International All rights reserved.
