Inductive Reactance of a coil depends on the frequency of the applied voltage as reactance is directly proportional to frequency. Inductive reactance is the property of an inductive coil that resists the change in alternating current (AC) through it and is similar to the opposition to direct current (DC) in a resistance. Thus far we…

All coils, inductors, chokes and transformers create a magnetic field around themselves consist of an Inductance in series with a Resistance forming an LR Series Circuit. Inductive coils and solenoids are not purely inductive devices, but instead consist of an inductance and resistance connected together to form a basic LR series circuit. In the first…

Inductors are said to be connected together in Parallel when both of their terminals are respectively connected to each terminal of another inductor or inductors. The voltage drop across all of the inductors in parallel will be the same. Then, Inductors in Parallel have a Common Voltage across them and in our example below the voltage across the inductors…

Inductors can be connected together in a series connection when the are daisy chained together sharing a common electrical current. These interconnections of inductors produce more complex networks whose overall inductance is a combination of the individual inductors. However, there are certain rules for connecting inductors in series or parallel and these are based on…

Mutual Inductance is the interaction of one coils magnetic field on another coil as it induces a voltage in the adjacent coil. Mutual inductance is a circuit parameter between two magnetically coupled coils and defines the ratio of a time-varying magnetic flux created by one coil being induced into a neighbouring second coil. Previously we…

Inductance is the name given to the property of a component that opposes the change of current flowing through it and even a straight piece of wire will have some inductance. The inductance of a coil refers to the electrical property the inductive coil has to oppose any change in the current flowing through it.…

An Inductor is a passive electrical component consisting of a coil of wire which is designed to take advantage of the relationship between magentism and electricity as a result of an electric current passing through the coil. In this tutorial we will see that the inductor is an electrical component used to introduce inductance into…
