Quick Answer: What Is The Condition Of Resonance?

Why is resonance so dangerous?

Resonant frequencies can also be disastrous if you build up too much vibrational energy in a system that can’t handle it, which is how sound alone at just the right pitch is capable of causing a wine glass to shatter.

A wine glass, stimulated by a continued sound at just the right pitch/frequency, will vibrate at….

What happens when XL XC?

If XL =Xc, then tan ∅ = 0 and the current is in phase with the voltage, and the circuit is known as a resonant circuit.

What is XL in inductor?

And it is denoted as XL. Inductive reactance is the resistance offered by the inductive circuit. It is the opposition to a changing current flow offered by an inductor.

What happens at resonance?

Some objects have two or more resonant frequencies. … 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 XC and XL?

There are two types of reactance: capacitive reactance (Xc) and inductive reactance (XL). The total reactance (X) is the difference between the two: Total Reactance, X = XL – Xc.

What is meant by resonance?

Resonance describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts.

Can resonance kill you?

This is also the resonant frequency of the body’s organs. At high volumes, infrasound can directly affect the human central nervous system, causing disorientation, anxiety, panic, bowel spasms, nausea, vomiting and eventually organ rupture or even death from prolonged exposure.

Where is resonance useful?

Where can make use of resonance? Resonance can be employed to maintain AC circuit oscillations at a constant frequency, just as a pendulum can be used to maintain constant oscillation speed in a timekeeping mechanism.

What is resonance and the conditions for resonance give examples?

Resonance is when the frequencies of forced vibrations on an object matches the object’s natural frequency, causing a dramatic increase in amplitude. … Some examples of resonance include: a vibrating metal rod, this forces the air column inside the rod to vibrate at the same frequencies.

What is the condition of resonance in LCR circuit?

Electrical resonance is said to take place in a series LCR circuit when the circuit allows maximum current for a given frequency of the source of alternating supply for which capacitive reactance becomes equal to the inductive reactance. The impedance of LCR circuit is minimum and hence current is maximum.

Why does amplitude increase at resonance?

Resonance is created by a periodic force driving a harmonic oscillator at its natural frequency. It is said that the device resonates. The less damping a system has, the greater the amplitude of the near resonance forced oscillations.

Why does resonance happen?

If an object is being forced to vibrate at its natural frequency, resonance will occur. This is what causes large amplitudes of vibration when a machine’s running speed is at or near a natural frequency even if the force inputs are low.

Is resonance good or bad?

Conclusion: The resonance frequency is useful In acoustics, a higher amplitude of sound waves means a higher sound pressure and thus a higher volume. Resonant frequencies are generally undesirable for loudspeakers.

How do you calculate XC and XL?

XL is called as inductive reactence and Xc is called as capacitive reactence. and the formulae[ XL = 2∏fL, XC = 1/2∏fC ] is given in that website.
