What is LC Circuit?
LC Circuit is also known as a “tank circuit” or “inductor-capacitor circuit”. LC Circuit is a simple electrical circuit that consists of two main components: an inductor and a capacitor. These components can further be added together in series or parallel configurations based on the required task at hand. An LC circuit is used to store electrical energy in the circuit with the help of magnetic resonance.
The energy or current in an LC circuit oscillates between the inductor and capacitor just like a pendulum swings back and forth. An LC circuit is used to store electrical energy in the circuit with the help of magnetic resonance. Resonance in an LC circuit occurs when the magnitude of inductive reactance and capacitive reactance in the LC circuit becomes equal. The frequency at which this occurs is known as resonant frequency.
The energy stored in an LC circuit gets exhausted if the source of energy is disconnected due to the internal resistance offered by the circuit as the current moves back and forth between the inductor and capacitor in an 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.
