What Is The Condition For Resonance?

What do you understand by series resonance What is the condition?

Series resonance is a resonance condition that usually occurs in series circuits, where the current becomes a maximum for a particular voltage.

In series resonance, the current is maximum at resonant frequency.

The series resonance current curve increases to a maximum at resonance then decreases as resonance is passed..

How do you calculate resonant frequency?

The term “L” corresponds to the length of the wave. Basically, this formula states the resonance frequency is equal to the wave velocity divided by the distance of the wavelength multiplied by the resonance frequency number the user is calculating for.

What is an example of resonance?

Pushing a person in a swing is a common example of resonance. The loaded swing, a pendulum, has a natural frequency of oscillation, its resonant frequency, and resists being pushed at a faster or slower rate.

How is Q factor calculated?

The Q factor of the pMUT can be determined by the real part of the impedance frequency spectrum, which is defined as Q = fr/Δf, where the resonance frequency fr is the frequency at which the real part of the impedance reaches its maximum, Δf is the width of the peak at its half height, so-called 3 dB bandwidth.

What is resonance curve?

: a curve whose abscissas are frequencies lying near to and on both sides of the natural frequency of a vibrating system and whose ordinates are the corresponding amplitudes of the near-resonant vibrations.

What is the frequency in resonance condition?

When the frequency increases, the value of XL increases, whereas the value of XC decreases. Similarly, when the frequency decreases, the value of XL decreases and the value of XC increases. Thus, to obtain the condition of series Resonance, the frequency is adjusted to fr, point P as shown in the curve below.

What is the importance of resonance?

The importance of resonance is that the circuit can either absorb or dissipate the maximum amount of energy at resonance. One practical example is used in a radio receiver. Many the frequencies from different radio stations are impinging on the radio’s antenna at the same time.

What are the applications of resonance?

One use for resonance is to establish a condition of stable frequency in circuits designed to produce AC signals. Usually, a parallel (tank) circuit is used for this purpose, with the capacitor and inductor directly connected together, exchanging energy between each other.

Why does resonance happen?

Light waves come from the vibration of charged particles. Objects, charged particles, and mechanical systems usually have a certain frequency at which they tend to vibrate. … Resonance occurs when the amplitude of an object’s oscillations are increased by the matching vibrations of another object.

What is the condition for series resonance?

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.

What is the simple definition of resonance?

1a : the quality or state of being resonant. b(1) : a vibration of large amplitude in a mechanical or electrical system caused by a relatively small periodic stimulus of the same or nearly the same period as the natural vibration period of the system.

Do humans have a resonant frequency?

By testing the response of the human body on a vibrating platform, many researchers found the human whole-body fundamental resonant frequency to be around 5 Hz. However, in recent years, an indirect method has been proposed which appears to increase the resonant frequency to approximately 10 Hz.

What is natural frequency and resonance?

Natural vibrations are different from forced vibrations which happen at the frequency of an applied force (forced frequency). If the forced frequency is equal to the natural frequency, the vibrations’ amplitude increases manyfold. This phenomenon is known as resonance.

What is meant by parallel resonance?

Parallel Resonance Circuit. Parallel resonance occurs when the supply frequency creates zero phase difference between the supply voltage and current producing a resistive circuit. In many ways a parallel resonance circuit is exactly the same as the series resonance circuit we looked at in the previous tutorial.
