Inductance, Inductance

Heavyside, O. Electrician. Feb. 12, 1886, p. 271. See reprint It is customary to use the symbol L for inductance, possibly in honour of the physicist Heinrich Lenz.

Although no boundaries are defined, this is often referred to as loose-, critical-, and over-coupling. When two tuned circuits are loosely coupled through mutual inductance, the bandwidth will be narrow. As the amount of mutual inductance increases, the bandwidth continues to grow. When the mutual inductance is increased beyond a critical point, the peak in the response curve begins to drop, and the center frequency will be attenuated more strongly than its direct sidebands. This is known as overcoupling.
