# What is the resonance condition?

Resonance in AC circuits implies a special frequency determined by the values of the resistance , capacitance , and inductance . For series resonance the condition of resonance is straightforward and it is characterized by minimum impedance and zero phase.

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 meant by series resonance?

series resonance. noun. the resonance that results when circuit elements are connected with their inductance and capacitance in series, so that the impedance of the combination falls to a minimum at the resonant frequencyCompare parallel resonance.

## What is the resonance test?

The distinct difference in response is a proven way to determine if an object is structurally acceptable. Several types of resonance testing are used today; the technique derived from the initial methodology is called the acoustic impact technique or ping testing.

## 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 = ƒr /BW.

## 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.

## What is cyclotron resonance?

Ion cyclotron resonance is a phenomenon related to the movement of ions in a magnetic field. It is used for accelerating ions in a cyclotron, and for measuring the masses of an ionized analyte in mass spectrometry, particularly with Fourier transform ion cyclotron resonance mass spectrometers.

## 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.

## What is resonance and what causes it?

The result of resonance is always a big vibration – that is, a loud sound. The vibrations of the aluminum force the air column inside of the rod to vibrate at its natural frequency. The match between the vibrations of the air column and one of the natural frequencies of the singing rod causes resonance.

## What is the resonance condition of a cyclotron?

The frequency of the applied voltage is kept exactly the same as the frequency of revolution of the proton, then every time the proton reaches the gap between the two dees, the electric field is reversed And proton receive a push and finally it accquires very high energy. This is called Cycloton’s Resonance Condition.

## How does resonance occur?

If that frequency happens to match the resonant frequency of the object it’s hitting, then you’ll get what’s called resonance. Resonance occurs when the amplitude of an object’s oscillations are increased by the matching vibrations of another object.

## What is meant by 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.”

## What is resonance in vibration analysis?

Many experts working in the field of vibration analysis will agree that resonance is a very common cause of excessive machine vibration. Resonance is the result of an external force vibrating at the same frequency as the natural frequency of a system.

## What is resonance and how does it work?

Resonance, An object free to vibrate tends to do so at a specific rate called the object’s natural, or resonant, frequency. Such an object will vibrate strongly when it is subjected to vibrations or regular impulses at a frequency equal to or very close to its natural frequency. This phenomenon is called resonance.

## 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.

## 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 sharpness of resonance?

Frequency response is a measure of the amplitude of an oscillation as a function of frequency. Sharpness of resonance is defined by the Q factor, which is related to how quickly the energy of the oscillating system decays.

## What is the resonance energy?

The resonance energy of a compound is a measure of the extra stability of the conjugated system compared to the corresponding number of isolated double bonds. This can be calculated from experimental measurements. This is the resonance energy for benzene.

## What is resonance in organic 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.

## 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.

## 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.
