What is meant by resonant frequency?
The resonant frequency can also be defined as the natural frequency of an object where it tends to vibrate at a higher amplitude. For example, you could feel a bridge “shake” if the collective oscillation force from vehicles caused it to vibrate at its frequency.
What is resonant frequency in electrical engineering?
The resonance frequency is defined as the frequency at which the impedance of the circuit is at a minimum. Equivalently, it can be defined as the frequency at which the impedance is purely real (that is, purely resistive).
What do you mean by resonant circuit and resonant frequency?
An electric circuit which has very low impedance at a certain frequency. Resonant circuits are used in radio and television tuners to pick out broadcast signals of specific frequencies.
What is the resonant frequency of AC circuit?
The resonant angular frequency is ω0=√1LC=√1(4.00×10−3H)(2.00×10−6F)=1.12×104rad/s. At this frequency, the average power transferred to the circuit is a maximum.
What is resonant frequency in AC circuit?
The resonant frequency of the circuit is the frequency at which the amplitude of the current is a maximum and the circuit would oscillate if not driven by a voltage source. By inspection, this corresponds to the angular frequency at which the impedance in Equation 12.5.1 is a minimum, or when. and. (12.5.3)
What is the use of resonant frequency?
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 is resonant frequency important?
The importance of resonance is that the circuit can either absorb or dissipate the maximum amount of energy at resonance. By varying the capacitance in a circuit (connected to the antenna) the circuit can be tuned so that the resonance frequency of the circuit is equal to the desired station frequency.
What does resonant frequency Class 12 mean?
Class 12 Physics Alternating Current. Resonance. Resonance. Resonance is defined as the tendency of the system to oscillate at greater amplitude at some frequencies than at others. It is common among the systems that have a tendency to oscillate at a particular frequency and that frequency is known as natural frequency …
What is resonant frequency Class 12?
Resonance is the phenomenon in the electrical circuit, where the output of the electrical circuit is maximum at one particular frequency. That particular frequency is known as the resonant frequency. At the resonant frequency, the capacitive reactance and inductive reactance are equal.
What is the formula for resonance frequency?
The resonance frequency of each vibration can be found using the formula fn = (v/ λn) = (nv/2L). The term λn stands for (2L/n) and the term L represents (n (λn)/2).
What is LC resonance?
Resonance occurs when an LC circuit is driven from an external source at an angular frequency ω 0 at which the inductive and capacitive reactances are equal in magnitude. The frequency at which this equality holds for the particular circuit is called the resonant frequency. The resonant frequency of the LC circuit is.
What is the Resonance Formula?
Resonance formula. The formula for resonance is: 2 * pi * f * L = 1 / (2 * pi * f * C) where: 2 * pi = 6.2832; f = frequency in hertz L = inductance in Henries and C = capacitance in Farads .
What is resonance frequency?
Resonance. In sound applications, a resonant frequency is a natural frequency of vibration determined by the physical parameters of the vibrating object. This same basic idea of physically determined natural frequencies applies throughout physics in mechanics, electricity and magnetism, and even throughout the realm of modern physics.
