A 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**.1

## 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.2

## 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.3

## 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.

## 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**.7

## 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.8

## 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**.9

## 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.
