Solid State 625
Presents the basic theory of inductors and inductance. Describes the fundamentals such as factors affecting inductance, CEMF, units of measurement, and how they are rated. Reveals how inductors are used in DC and AC circuits. Supports theory with elevator-related examples such as brake circuits, field windings, AC solenoids, and line noise suppressors. Describes the process for testing inductors. Presents methods for isolating open, externally shorted, and internally shorted windings.
