The sharpness of resonance is defined using the Q factor which explains how fast energy decay in an oscillating system. The sharpness of resonance depends upon: Damping: Effect due to which there is a reduction in amplitude of vibrations. Amplitude: Maximum displacement of a point on a vibrating body which is measured from its equilibrium position.
- What is resonance?Resonance is defined as the tendency of a system to vibrate with an increase in amplitude at the excitation of frequencies.
- Define resonant frequency.Resonance frequency or resonant frequency is the maximum frequency at which the amplitude is relatively maximum.

As the amplitude increases with the excitation of frequencies, a system's tendency to vibrate also increases. This is defined as Resonance. The maximum frequency following which the amplitude is also maximum is called resonant frequency. To define the Sharpness of Resonance, the Q factor is used. When the matching vibrations of an object make anoth...
The depletion of an oscillatingwavewith respect to time is called the sharpness of the Resonance. It relates to the energy decay that happens in an oscillating system. It is mainly defined by the Q factor. The Sharpness of Resonance is dependent on mainly two factors. These are: 1. Amplitude 2. Damping Amplitude: It is defined as the height of a wa...
After knowing Resonance and Sharpness of Resonance, let us help you understand what Q factor is and its use. Q factor stands for the quality factor. It does not have any dimensions. It is used to characterise the centre frequency and bandwidth of the resonator and the underdamped resonator. It is represented mathematically as: Q= Restore/Lostper cy...
The phenomenon of Resonance can be observed in an LCR Circuit arranged in series. The circuit is in Resonance during its Resonance frequency fr which happens when XL=Xc. The resonant frequency is given by the formula: fr= 1/2π√LC Now, according to the conditions: When current is maximum: f=fr The following conditions are applicable in the given ser...
The following aspects are observed when the circuit is in Resonance: 1. Z=R, this implies that during Resonance, the impedance of the circuit is equal to R and is at its minimum value. 2. The RMS (root mean square) value in the circuit is at its maximum, and the Resonance is equal to Vrms/R. 3. The current and applied voltage are in phase. 4. The p...
In an AC circuit, the power factor is defined as the ratio of true power dissipation to the apparent power dissipation, represented using: cos Φ= R/Z The power factor for the AC circuit lies between the range of 0 and 1. Purely inductive circuit= 0 Purely resistive circuit= 1
May 16, 2023 · Sharpness of Resonance is a measure of the energy decay in resonating systems. It depends on the time. It is quantitatively stated by the Q-Factor. The sharpness of resonance depends on two factors which are as follows: Amplitude – The amplitude of any wave is inversely proportional to the sharpness of resonance.
Oct 13, 2022 · What is resonance and sharpness of resonance? Resonance is defined as the large chosen response of the system or material that vibrates in phase or step with an external applicable force of oscillation.
May 22, 2022 · At this point we can more precisely define \(Q\). Specifically, the “sharpness” of the curve is related to the half-power or “−3 dB” frequencies, \(f_1\) and \(f_2\). 1 These are the frequencies at which the current (assuming voltage source drive) falls off to 0.707 of the maximum value at resonance.
Equivalently the sharpness of the resonance increases with decreasing R. For a fixed L and C, a decrease in R corresponds to a narrower resonance and thus a higher selectivity regarding the frequency range that can be passed by the circuit.
Bandwidth of a Series Resonance Circuit. The frequency response of the circuits current magnitude above, relates to the “sharpness” of the resonance in a series resonance circuit. The sharpness of the peak is measured quantitatively and is called the Quality factor, Q of the circuit.
