# Quick Answer: What Is The Use Of LCR Circuit?

## How does RLC circuit work?

RLC Circuit.

This is an RLC circuit, which is an oscillating circuit consisting of a resistor, capacitor, and inductor connected in series.

The voltage in the capacitor eventually causes the current flow to stop and then flow in the opposite direction.

The result is an oscillation, or resonance..

## What is an acceptor circuit and where it is used?

Acceptor circuit provides the maximum response to currents at its resonant frequency. Series resonance circuit is known as acceptor circuit because the impedance at the resonance is at its minimum so as to accept the current easily such that the frequency of the accepted current is equal to the resonant frequency.

## What is the definition of impedance?

the total opposition to alternating current by an electric circuit, equal to the square root of the sum of the squares of the resistance and reactance of the circuit and usually expressed in ohms. Symbol: Z. Also called mechanical impedance.

## Why the series resonance circuit is called an acceptor circuit and the parallel resonance circuit is called Rejector circuit?

Answer. – Series resonance circuit is aka acceptor circuit as it accepts current at resonant frequency. … – Parallel resonance circuit is aka rejector circuit as its current is minimum at resonant frequency. – Impedance is maximum here.

## What is the power factor of an LCR circuit?

This therefore gives us: Power Factor = Real Power/Apparent Power, or p.f. = W/VA. Then the cosine of the resulting angle between the current and voltage is the power factor. Generally power factor is expressed as a percentage, for example 95%, but can also be expressed as a decimal value, for example 0.95.

## What is the full form of LCR?

What Is the Liquidity Coverage Ratio – LCR? The liquidity coverage ratio (LCR) refers to the proportion of highly liquid assets held by financial institutions, to ensure their ongoing ability to meet short-term obligations.

## What is series LCR circuit?

LCR Circuit : Analysis Of A LCR Series Circuit An LCR circuit, also known as a resonant circuit, tuned circuit, or an RLC circuit, is an electrical circuit consisting of an inductor (L), capacitor (C) and resistor (R) connected in series or parallel. … But the resistance, current and voltage phasors are always in phase.

## What is a tank circuit used for?

Applications of Tank Circuit These circuits are used for tuning transmitters & receivers of radio. Once these circuits get charge then generate a precise frequency. For example, once you turn on a radio toward a particular station, the charge can be changed on a circuit then it vibrates at that frequency.

## What is Q factor in RLC circuit?

The quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation meaning that it is a ratio of resonant frequency to bandwidth and the higher the circuit Q, the smaller the bandwidth, Q = ƒr /BW.

## What is resonance formula?

Since the circuit is at resonance, the impedance is equal to the resistor. Then, the peak current is calculated by the voltage divided by the resistance. Solution. The resonant frequency is found from Equation 15.6. 5: f0=12π√1LC=12π√1(3.00×10−3H)(8.00×10−4F)=1.03×102Hz.

## What is bandwidth in LCR circuit?

An important property of a resonant circuit is its bandwidth. Bandwidth is defined as the size of frequency range that is passed or rejected by the tuned circuit. … The resonant circuit below consists of a resistor, an inductor and a capacitor in series with a current meter and a voltage source.
