What is a simple definition of resonance?

In physics, resonance is the tendency of a system to vibrate with increasing amplitudes at some frequencies of excitation. These are known as the system’s resonant frequencies (or resonance frequencies). The resonator may have a fundamental frequency and any number of harmonics.

What is the resonance circuit?

[ rĕz′ə-nənt ] 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.

What is resonance in vibration engineering?

A vibration resonance occurs when equipment or a product is exposed to an external forced vibration occurring at one or more of its natural frequencies. The resulting product response vibration is amplified and can be huge! Vibration resonances can cause severe damage to products and significantly shorten their life.

What is resonance in electrical engineering?

Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other. In some circuits, this happens when the impedance between the input and output of the circuit is almost zero and the transfer function is close to one.

What is the importance of resonance in engineering?

Resonance serves to amplify the vibration due to whatever vibration force is present at (or near) that resonant frequency. It is important to note that resonance does not cause vibration, it amplifies it.

What is the use 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.

What is electrical resonance in series LCR circuit?

Resonance is the phenomenon in the circuit when the output of that electric circuit is maximum at one particular frequency. In LCR series circuits, resonance occurs when the value of inductive and capacitive reactances have equal magnitude but have a phase difference of 180°. Thus, they cancel each other.

What is resonance and its conditions?

Resonance is a special case of force vibration when the frequency of external applied a periodic force on a body is equal to its natural frequency the body really been to vibrate with an increase amplitude this vibration of large amplitude are called resonant vibration and phenomenon is know as resonance .

What is meant by electrical resonance?

What is mechanical resonance and how does it work?

Mechanical resonance can be defined as the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system’s natural frequency of vibration (its resonance frequency or resonant frequency) than it does at other frequencies.

What is the resonance frequency of the system?

The resonant frequency, f, of the system is given by: m being the mass of the suspended weight and k is the spring constant. In many circuits, electrical resonance frequency is the result of impedance between circuit input and output being equal to zero, and transfer function being near to one.

What is acoustic resonance?

Acoustic resonance can create large, destructive oscillations when the pitch of a sound matches the resonant frequency of a wine glass for instance. In the case of stringed instruments, if we consider a wave travelling along the string with speed, v, the resonant frequency, f, is given by:

What is an example of structural resonance?

A good example of structural resonance is the reed frequency vibration that often occurs with vertical turbine pumps that have a motor mounted on top of the discharge elbow. The machine components can also be resonant.
