AC1 Fundamentals Unit 3 – Inductance
NEW TERMS AND WORDS
inductance (L) - one property of a conductor that opposes change in current flow.
counter electromotive force (cemf) - a 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.
