Differbetween
As a parallel resonance circuit only functions on resonant frequency, this type of circuit is also known as an Rejecter Circuit because at resonance, the impedance of the circuit is at its maximum thereby suppressing or rejecting the current whose frequency is equal to its resonant frequency.

Why is current maximum at the resonant frequency?
At resonance the impedance of the circuit is equal to the resistance value as Z = R. ... Because impedance is minimum and current is maximum, series resonance circuits are also called Acceptor Circuits.
Why parallel circuit is known as current magnification though it has minimum current at the time of resonance?
Current flowing through Capacitor
Note − Parallel resonance RLC circuit is called as current magnification circuit. Because, the magnitude of current flowing through inductor and capacitor is equal to Q times the input sinusoidal current I.
What is resonance impedance?
At resonance, the series impedance of the two elements is at a minimum and the parallel impedance is at maximum. Resonance is used for tuning and filtering, because it occurs at a particular frequency for given values of inductance and capacitance.
How do you find the impedance of a parallel RLC circuit?
The total impedance, Z of a parallel RLC circuit is calculated using the current of the circuit similar to that for a DC parallel circuit, the difference this time is that admittance is used instead of impedance. Consider the parallel RLC circuit below.
What happens resonant frequency?
Resonant frequency is the oscillation of a system at its natural or unforced resonance. Resonance occurs when a system is able to store and easily transfer energy between different storage modes, such as Kinetic energy or Potential energy as you would find with a simple pendulum.
What causes resonance frequency?
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.
What does resonance mean?
1a : the quality or state of being resonant. b(1) : a vibration of large amplitude in a mechanical or electrical system caused by a relatively small periodic stimulus of the same or nearly the same period as the natural vibration period of the system.
What is meant by quality factor?
In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. ... Q factor is alternatively defined as the ratio of a resonator's centre frequency to its bandwidth when subject to an oscillating driving force.
What is dynamic impedance?
[dī¦nam·ik im′ped·əns] (electricity) The impedance of a circuit having an inductance and a capacitance in parallel at the frequency at which this impedance has a maximum value. Also known as rejector impedance.
What is the resonance condition?
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.
What is meant by impedance?
In electrical engineering, electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. ... Impedance is a complex number, with the same units as resistance, for which the SI unit is the ohm (Ω).
How do you calculate resonant frequency?
This resonant frequency is represented by the following equation:
- f = 1 / (2π √L C)
- f = 1 / (2π √L C) Resonant Frequency [Hz]
- L = 1 / (4π2 f2 C) Inductance [H]
- C = 1 / (4π2 f2 L) Capacitance [F]
