The AC Inductive Circuits Handbook is a comprehensive reference for engineers and students. It covers in-depth insights into AC circuits with inductors, offering practical guidance, analysis techniques, and formulae for designing and troubleshooting circuits. An indispensable resource for mastering inductive components in electrical systems.
Inductors do not behave the same as resistors. Whereas resistors simply oppose the ﬂow of electrons through them (by dropping a voltage directly proportional to the current), inductors oppose changes in current through them, by dropping a voltage directly proportional to the rate of change of current. In accordance with Lenz’s Law, this induced voltage is always of such a polarity as to try to maintain current at its present value. That is, if current is increasing in magnitude, the induced voltage will “push against” the electron ﬂow; if current is decreas- ing, the polarity will reverse and “push with” the electron ﬂow to oppose the decrease. This opposition to current change is called reactance, rather than resistance.
