Inductor

What is an Inductor?

An inductor is a passive electronic component that stores energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More in a magnetic field when electric current flows through it. As current passes through the inductor a magnetic field is created around it, just like a coil of wire. This magnetic field can store energy temporarily and release it when needed.

How An Inductor Works:

The operation of an inductor relies on Faraday’s Law of Electromagnetic Induction . This law states hat whenever there is a change in magnetic flux linking a circuit, an e.m.f is induced, the strength of which is directly proportional to the rate of change of the flux linking the circuit

As shown in Fig. 6.3.1 above, a lamp, a coil of wire (inductor), and a switch are connected to a battery. The lamp lights up normally without the inductor in the circuit, but when the inductor is connected as shown the circuit behaves differently.

The resistance of the lamp is much lower than that of the lamp. When the switch is closed, most of the
