The Inductor and the Effects of Inductance on a Coil
In its most basic form, an Inductor is nothing more than a coil of wire wound around a central core. For most coils the current, ( i ) flowing through the coil produces a magnetic flux, ( NΦ ) around it that is proportional to this flow of electrical current. An Inductor, also called a choke, is another passive type electrical component consisting of a coil of wire …
