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 is resonance in electricity?

**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.

## What is the use of resonance?

This phenomenon is called resonance. Through resonance, a comparatively weak vibration in one object can cause a strong vibration in another. By analogy, the term resonance is also used to describe the phenomenon by which an

**oscillating**electric current is strengthened by an electric signal of a specific frequency.2

## What do you mean by resonant circuit?

**resonant circuit**. [rĕz′?-n?nt] An electric

**circuit**which has very low impedance at a certain

**frequency**.

**Resonant circuits**are often built using an inductor, such as a coil, connected in parallel to a capacitor.

## How energy is stored in a capacitor?

The

**energy stored**on a**capacitor**can be expressed in terms of the work done by the battery. Voltage represents**energy**per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the**capacitor**. But the battery**energy**output is QV!4

## 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.

## What do you mean by resonance in chemistry?

In

**chemistry**,**resonance**or mesomerism is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis structure.6

## What is resonance in RLC 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.7

## What is the formula for resonance?

**Resonance**occurs when capacitive and inductive reactances are equal to each other. For a tank circuit with no resistance (R),

**resonant**frequency can be calculated with the following

**formula**: The total impedance of a parallel LC circuit approaches infinity as the power supply frequency approaches

**resonance**.

## What is the 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.

## What is the meaning of LC oscillators?

**LC oscillator**is a type of

**oscillator**where a

**LC**(inductor-capacitor) tank circuit is used for giving the required positive feedback for sustaining the oscillations. The

**LC**tank circuit is also termed as

**LC**resonant circuit or

**LC**tuned circuit.

## What is the definition of resonant frequency?

In physics,

**resonance**is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific**frequencies**.**Frequencies**at which the response amplitude is a relative maximum are known as the system's**resonant frequencies**or**resonance frequencies**.11

## What is Q 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.12

## 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.13

## 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.

14

## What is Q factor of resonant 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 = ƒ_{r}/BW.15

## How is AC produced?

**AC**can be

**produced**using a device called an alternator. This device is a special type of electrical generator designed to

**produce**alternating current. A loop of wire is spun inside of a magnetic field, which induces a current along the wire.

16

## 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**.17

## What is meant by resonance in chemistry?

In

**chemistry**,**resonance**or mesomerism is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis structure. An isomer is a molecule with the same**chemical**formula but with different arrangements of atoms in space.18

## What is the use of resonance circuit?

The most common application of tank circuits is tuning radio transmitters and receivers. For example, when we tune a radio to a particular station, the LC circuits are set at resonance for that particular carrier frequency. A

**parallel**resonant circuit can be used as load impedance in output circuits of RF amplifiers.19

## What do you mean by resonance curve?

A

**resonance curve**is a graph of the response of an atomic system to electromagnetic radiation as a function of the frequency of the radiation. The simplest example of a**resonance curve**is the single peak that appears as a laser's frequency is scanned through the difference between two energy levels in the atoms.
