# RLC circuit

An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.

In RLC circuit, the most fundamental elements of a resistor, inductor and capacitor are connected across a voltage supply. All of these elements are linear and passive in nature. Passive components are ones that consume energy rather than producing it; linear elements are those which have a linear relationship between voltage and current.

Series RLC circuits consist of a resistance, a capacitance and an inductance connected in series across an alternating supply Thus far we have seen that the three basic passive components of: Resistance, Inductance, and Capacitance have very different phase relationships to each other when connected to a sinusoidal alternating supply.

An RLC series circuit with an AC voltage source. The combined effect of resistance R, inductive reactance XL, and capacitive reactance XC is defined to be impedance, an AC analogue to resistance in a DC circuit. Current, voltage, and impedance in an RLC circuit are related by an AC version of Ohm's law:

When a resistor, inductorand capacitor are connected together in parallel or series combination, it operates as an oscillator circuit (known as RLC Circuits) whose equations are given below in different scenarios as follow:

In a parallel RLC circuit containing a resistor, an inductor and a capacitor the circuit current IS is the phasor sum made up of three components, IR, IL and IC with the supply voltage common to all three. Since the supply voltage is common to all three components it is used as the horizontal reference when constructing a current triangle.

RLC Series Circuit The RLC series circuit is a very important example of a resonant circuit.

Selectivity and Q of a Circuit Resonant circuits are used to respond selectively to signals of a given frequency while discriminating against signals of different frequencies. If the response of the circuit is more narrowly peaked around the chosen frequency, we say that the circuit has higher "selectivity".

An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel.

RLC circuit analysis forms the language used to build and understand circuit models for linear time-invariant (LTI) systems with reactive impedance. Building a circuit model for a complex electrical system takes some experience and foresight, where real circuit elements and parasitics are combined to form an equivalent RLC network.

A series RLC circuit consists of a resistor R, an inductor L and a capacitor C connected in series. The sequence of letters in the circuit name can be different: RLC, RCL, LCR, etc. Like a pure series LC circuit, the RLC circuit can resonate at a resonant frequency and the resistor increases the decay of the oscillations at this frequency.

As we'll see, the $$RLC$$ circuit is an electrical analog of a spring-mass system with damping. Nothing happens while the switch is open (dashed line). When the switch is closed (solid line) we say that the circuit is closed. Differences in electrical potential in a closed circuit cause current to flow in the circuit.
