LC CIRCUIT Meaning and
Definition
-
An LC circuit refers to a type of electrical circuit consisting of an inductor (L) and a capacitor (C) connected in a closed loop. The inductor is a passive electrical component that stores energy in a magnetic field when current passes through it. On the other hand, a capacitor is an electronic component that stores electrical energy in an electric field.
By combining both components, an LC circuit has the ability to store energy oscillating between the capacitor and the inductor. When a voltage source is connected to the circuit, the capacitor stores energy in the form of an electric field, causing current to flow through the inductor. As the inductor resists changes in current, the energy is then transferred back to the capacitor. This back-and-forth transfer of energy creates an oscillating current in the circuit.
The behavior of an LC circuit is characterized by its resonant frequency, which occurs when the inductive and capacitive reactances cancel each other out, resulting in a maximum current flow. This resonance phenomenon allows LC circuits to find applications in various electronic devices, such as radio receivers, oscillators, and filters.
Overall, an LC circuit is an electrical circuit that incorporates an inductor and a capacitor, creating a system that stores and oscillates energy between the two components. This circuit configuration plays a crucial role in many electronic applications, capitalizing on the resonance phenomenon to achieve desired electrical behavior.
Etymology of LC CIRCUIT
The term "LC circuit" is derived from the combination of the symbols and abbreviations used to represent its components.
"L" stands for inductance, which is a property of an electrical circuit that creates a magnetic field when an electric current flows through it. It is represented by the symbol "L" and is measured in henries (H).
"C" stands for capacitance, which is a property of an electrical circuit that stores electric charge. It is represented by the symbol "C" and is measured in farads (F).
Together, these components form an LC circuit, also known as a tank circuit or oscillatory circuit, as it is often used in electronic oscillators and radio frequency applications. The term "LC circuit" reflects the combination of the symbols used to represent inductance and capacitance in the circuit.
