What is Inductor?
An inductor is an electrical component that is used to store energy in the form of magnetic energy. It is widely used in many electronics and electrical appliances. Inductor can also be called as choke coil. The strength of inductor is measured in terms of inductance and depends on various factors such as shape of inductor, number of turns in inductor, material of inductor and space between the turns in the inductor coil. Inductance of an inductor is measured in Henry (H).
Inductance in LC Circuit
Inductance in an LC circuit is the measure of the magnitude of the inductor connected in the LC circuit. SI unit of inductance is Henry (H) and the inductance of LC circuit is represented by L. It is calculated as:
L = μ0 N2 A/l
Where,
- L is the inductance in henrys (H)
- μ₀ is the permeability of free space, [μ₀ = 4π × 10-7 H/m]
- N is the number of turns of wire in the coil
- A is the cross-sectional area of the coil in square meters (m²)
- l is the length of the coil in meters (m)
LC Circuits
LC Circuit is a special type of electric circuit that is made up of an Inductor and a Capacitor. The inductor is represented by using the symbol L whereas the capacitor is represented using the symbol C. Hence, the name LC Circuit. LC Circuit acts as a major electric component in various devices such as oscillators, tuners, and filters. Thus LC circuit finds a number of applications in daily life. In this article, we shall discuss the LC circuit in detail.
