The resonant frequency for a driven RLC circuit is the same as a circuit in which there is no damping, hence undamped resonant frequency. The resonant frequency peak amplitude, on the other hand, does depend on the value of the resistor and is described as the damped resonant frequency.
The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...
In accordance with new definition (6), the value of the inductive coupling coefficient of resonant LC-circuits is expressed by formula (4) as before. It has a positive value when L m > 0 {\displaystyle L_{m}>0} and a negative value when L m < 0. {\displaystyle L_{m}<0.}
The frequency at which this equality holds for the particular circuit is called the resonant frequency. The resonant frequency of the LC circuit is =, where L is the inductance in henries, and C is the capacitance in farads. The angular frequency ω 0 has units of radians per second.
Position vector r is a point to calculate the electric field; r ... Circuit resonant frequency ... RLC circuits: Circuit equation
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.
Such resonant circuits are also called RLC circuits after the circuit symbols for the components. A distributed-parameter resonator has capacitance, inductance, and resistance that cannot be isolated into separate lumped capacitors, inductors, or resistors. An example of this, much used in filtering, is the helical resonator.
A resistor–inductor circuit (RL circuit), or RL filter or RL network, is an electric circuit composed of resistors and inductors driven by a voltage or current source. [1] A first-order RL circuit is composed of one resistor and one inductor, either in series driven by a voltage source or in parallel driven by a current source.
