LC Circuit
1. What is an LC circuit?
An LC circuit is a special type of circuit which is made by connecting an inductor and a capacitor either in series or in parallel.
2. What does Resonance means in an LC Circuit?
Resonance in an LC circuit refers to the condition when the magnitude of capacitance and inductance in the LC circuit becomes equal.
3. What are the Uses of LC Circuit in Real Life?
LC circuits are used for following purposes:
- They are used to generate signals at a specific frequency
- They are used in induction heating circuits.
4. How to Calculate Resonant Frequency in LC Circuit?
The expression used to calculate the resonance in LC circuit is f = 1/2π√LC where L and C are the inductance and capacitance in LC circuit and f is the resonant frequency.
5. What do you Mean by Quality factor of LC Circuit?
Quality factor or Q factor of an LC circuit is a measure of the goodness of the LC circuit an determines how efficiently the energy is transferred in a given LC circuit.

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.
