Join Barron Stone for an in-depth discussion in this video Protect against flyback voltage, part of Electronics Foundations: Semiconductor Devices.
- [Instructor] An inductor is an electrical component…that stores energy in a magnetic field…when current flows through it.…And the inductor will oppose any changes…to the amount of current passing through it…by very rapidly absorbing or releasing that energy.…An inductor wants the current through it to remain constant.…Now it's not just inductors that do that.…There are lots of electrical components…that exhibit inductive behavior such as motors.…An electric motor contains a bunch…of tightly wound coils of wire, much like an inductor,…and it stores and releases energy in a similar way.…
From an electrical standpoint, a motor looks similar…to a resistor and an inductor in series with each other.…Now that's not saying that if you stick a resistor…and an inductor together you suddenly have a motor.…They're very different components.…But when a motor is used in a circuit,…electrically to the rest of the circuit,…it behaves similar to a resistor and an inductor.…As long as the current from the power supplier…remains constant, the inductive aspect…
