Why parallel LCR is called Rejector circuit?

As a parallel resonance circuit only functions on resonant frequency, this type of circuit is also known as an Rejecter Circuit because at resonance, the impedance of the circuit is at its maximum thereby suppressing or rejecting the current whose frequency is equal to its resonant frequency.

What are uses of series and parallel resonant circuits?

A series resonant circuit provides voltage magnification. A parallel resonant circuit provides current magnification. A parallel resonant circuit can be used as load impedance in output circuits of RF amplifiers. Due to high impedance, the gain of amplifier is maximum at resonant frequency.

Why is series LCR circuit an acceptor circuit?

Series Circuit Current at Resonance As a series resonance circuit only functions on resonant frequency, this type of circuit is also known as an Acceptor Circuit because at resonance, the impedance of the circuit is at its minimum so easily accepts the current whose frequency is equal to its resonant frequency.

What is an LCR 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. The LCR circuit analysis can be understood better in terms of phasors. A phasor is a rotating quantity. Current Vs Voltage Graph

What are the applications of resonance of series and parallel LC circuits?

The applications of the resonance of the series and parallel LC circuits mainly involve in communications systems and signal processing The common application of an LC circuit is, tuning radio TXs and RXs. For instance, when we tune a radio to an exact station, then the circuit will set at resonance for that specific carrier frequency.

What is the impedance of a parallel LC tank circuit at resonance?

Also at resonance the parallel LC tank circuit acts like an open circuit with the circuit current being determined by the resistor, R only. So the total impedance of a parallel resonance circuit at resonance becomes just the value of the resistance in the circuit and Z = R as shown.

What is the phase difference between capacitor and resistor in series LCR?

What is the phase difference between the current in the capacitor and the current in the resistor in a series LCR circuit? The voltage across the capacitor lags the current in the circuit by 900. Hence, the phase difference between the voltage across the capacitor and the current in the circuit is 900.
