# Quick Answer: How Does RLC Circuit Work?

## How do you analyze an RLC circuit?

For a series RLC circuit, and impedance triangle can be drawn by dividing each side of the voltage triangle by its current, I.

The voltage drop across the resistive element is equal to I*R, the voltage across the two reactive elements is I*X = I*XL – I*XC while the source voltage is equal to I*Z..

## Why do we use RLC circuit?

RLC circuits have many applications as oscillator circuits. Radio receivers and television sets use them for tuning to select a narrow frequency range from ambient radio waves. … An RLC circuit can be used as a band-pass filter, band-stop filter, low-pass filter or high-pass filter.

## Is LCR and RLC circuit same?

A RLC circuit (also known as a resonant circuit, tuned circuit, or LCR circuit) is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. This configuration forms a harmonic oscillator.

## What is the transfer function of a circuit?

The Transfer Function of a circuit is defined as the ratio of the output signal to the input signal in the frequency domain, and it applies only to linear time-invariant systems.

## How do you find the transfer function of a circuit?

The transfer function H(s) of a circuit is defined as: H(s) = The transfer function of a circuit = Transform of the output Transform of the input = Phasor of the output Phasor of the input . RC . Transfer function is normally expressed in a form where the coefficient of highest power in the denominator is unity (one).

## How do you solve a RLC circuit using Laplace transform?

Analyze an RLC Circuit Using Laplace MethodsDevelop the differential equation in the time-domain using Kirchhoff’s laws and element equations.Apply the Laplace transformation of the differential equation to put the equation in the s-domain.Algebraically solve for the solution, or response transform.More items…

## How do you find the maximum current in a RLC circuit?

That maximum current is equal to 28.2885 volts divided by 9.936 ohms. That value is equal to 2.847 amps. That’s the maximum current in this circuit.

## What is time constant of RLC circuit?

For series RLC circuit Time Constant is 2L/R and for parallel RLC circuit Time Constant is 2RC.
