AnswersDriveA series resonance 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 or we can say that it functions mainly at resonance.
What is a parallel 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.

What do you mean by inductor?
An inductor is a passive electronic component that storesenergy in the form of a magnetic field. In its simplest form, an inductor consistsof a wire loop or coil. The inductance is directly proportional to the number ofturns in the coil.

What is quality factor in resonance?
The Q, or quality, factor of a resonant circuit is a measure of the “goodness” or quality of a resonant circuit. A higher value for this figure of merit corresponds to a more narrow bandwith, which is desirable in many applications.

What is the reactance?
In electrical and electronic systems, reactance is the opposition of a circuit element to a change in current or voltage, due to that element's inductance or capacitance.
4
What is meant by the reactance of a capacitor?
Capacitive reactance (symbol XC) is a measure of a capacitor's opposition to AC (alternating current). Like resistance it is measured in ohms, but reactance is more complex than resistance because its value depends on the frequency (f) of the signal passing through the capacitor.
5
What is the inductive reactance of A?
Inductive reactance is the name given to the opposition to a changing current flow. This impedance is measured in ohms, just like resistance. In inductors, voltage leads current by 90 degrees.
6
What do you mean by Wattless current?
A Wattless Current can be defined in following way: The current in an AC circuit is said to be Wattless Current when the average power consumed in such circuit corresponds to Zero.Such current is also called as Idle Current.

What is a parallel resonant circuit?
The resonance of a parallel RLC circuit is a bit more involved than the series resonance. The resonant frequency can be defined in three different ways, which converge on the same expression as the series resonant frequency if the resistance of the circuit is small. Impedance definition. Phase definition. Index.

Why a series resonant circuit is called a acceptor circuit?
The most prominent feature of the frequency response of a resonant circuit is a sharp resonant peak in its amplitude characteristics. Because impedance is minimum and current is maximum, series resonance circuits are also called Acceptor Circuits.

What is an LCR 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 circuit forms a harmonic oscillator for current, and resonates in a similar way as an LC circuit.
10
What is the difference between a series and a parallel circuit?
In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
11
Why current is minimum in parallel resonance?
Resonance occurs in a parallel RLC circuit when the total circuit current is “in-phase” with the supply voltage as the two reactive components cancel each other out. At resonance the admittance of the circuit is at its minimum and is equal to the conductance of the circuit.
12
What is the resonant circuit?
An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together.
13
Why current is maximum in series resonance?
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.
14
What is the resonant frequency?
In sound applications, a resonant frequency is a natural frequency of vibration determined by the physical parameters of the vibrating object. It is easy to get an object to vibrate at its resonant frequencies, hard to get it to vibrate at other frequencies.
15
What is meant by natural frequency and resonance?
Definition of Resonance - "The increase in amplitude of oscillation of an electric or mechanical system exposed to a periodic force whose frequency is equal or very close to the natural undamped frequency of the system."
16
What do you mean by electrical resonance?
resonance: In an electrical circuit, the condition that exists when the inductive reactance and the capacitive reactance are of equal magnitude, causing electrical energy to oscillate between the magnetic field of the inductor and the electric field of the capacitor.
17
What is the Q factor?
The Q factor is a dimensionless parameter that indicates the energy losses within a resonant element which could be anything from a mechanical pendulum, an element in a mechanical structure, or within electronic circuit such as a resonant circuit. In particular Q is often used in association with an inductor.
