What are RLC circuits used for?
RLC circuits are often used as oscillator circuits because they produce sine waves, square waves, or triangle waves. These are oscillating electronic signals that can convert direct current into alternating current or work as a low-pass filter, high-pass filter, band-stop filter, and band-pass filter.Read more

what is the use of resonant circuit? Definition of resonant circuit
Resonant circuits are used in radio and television tuners to pick out broadcast signals of specific frequencies.
Another question to consider, what is rlc resonance circuit? The resonance of a series RLC circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase. The sharp minimum in impedance which occurs is useful in tuning applications.
What are the application of a acceptor circuit?
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 happen when a series RLC circuit is in resonance?
At resonance in series RLC circuit, both inductive and capacitive reactance cancel each other and we know that in series circuit, the current flowing through all the elements is same, So the voltage across inductor and capacitor is equal in magnitude and opposite in direction and thereby they cancel each other.
Is LCR and RLC circuit same?
Is there a difference between RLC circuit and LCR circuit? There is no difference between an RLC circuit and an LCR circuit except for the order of the symbol represented in the circuit diagram.
What is the current in the series RLC circuit at resonance What is the reason for that?
Therefore, current flowing through series RLC circuit at resonance is I=VR. At resonance, the impedance of series RLC circuit reaches to minimum value. Hence, the maximum current flows through this circuit at resonance.
What is RLC acceptor circuit?
A resistance, inductance and a capacitance in series is called an "acceptor" circuit, presumably because, for some combination of the parameters, the magnitude of the inductance is a minimum, and so current is accepted most readily.
Why is it called 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.
Why is resonance called voltage resonance?
In series circuit, current is common to both capacitor and inductor, while voltages across these two are equal and opposite, and cancel each other. This is voltage resonance.
What are the practical applications of series RLC resonance circuits in real life?
How the RLC series circuit behaves for the frequencies above and below the resonant frequencies?
2. How the RLC series circuit behaves for the frequencies above and below the resonant frequencies. For frequencies below resonant frequency, the capacitive reactance is more than the inductive reactance. Therefore the equivalent reactance is equal to capacitive and the circuit behaves like a RC circuit.
Why parallel resonance 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.
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.
What is series and parallel RLC circuit?
In series RLC circuit, the current flowing through all the three components i.e the resistor, inductor and capacitor remains the same, but in parallel circuit, the voltage across each element remains the same and the current gets divided in each component depending upon the impedance of each component.
What is XL and XC in RLC circuit?
In series RLC circuit, the condition XL(Inductive reactance) = XC (Capacitive reactance) is called resonance condition. In this condition the inductive reactance get cancelled by capacitive reactance. So,the entire RLC series circuit just acts as a resistive circuit. So,the power factor is unity.
What is the resonance frequency of RLC series circuit?
f0=12π√LC f 0 = 1 2 π L C , where f0 is the resonant frequency of an RLC series circuit. This is also the natural frequency at which the circuit would oscillate if not driven by the voltage source.
What is difference between acceptor circuit and Rejector circuit?
- Series resonance circuit is aka acceptor circuit as it accepts current at resonant frequency. - Impedance is minimum here. - Voltage is magnified in acceptor circuit. - Parallel resonance circuit is aka rejector circuit as its current is minimum at resonant frequency.
