A parallel resonant circuit has low impedance, when non resonant; however the impedance rises sharply, as the circuit comes to resonance.
tuned circuit consists of resistance and capacitor so this one RC circuit formula to be used f = 1/ 2 pi RC
For to keep the resonant frequancy constant L*C has to stay same. Lets say if you double L you have to divide C by 2 to keep the same resonant frequency. If only L increases Resonant frequency decrease, this is same for C.
Because the series resonant circuit has the lowest possible impedance at resonance frequency, thus allowing the AC current to circulate through it. At resonance frequency, XC=XL and XL-XC = 0. Therefore, the only electrical characteristic left in the circuit to oppose current is the internal resistance of the two components. Hence, at resonance frequency, Z = R. Note: This effect is probably better seen with vectors. Clarification: Resonant circuits come in two flavors, series and parallel. Series resonant circuits do have an impedance equal to zero at the resonant frequency. This characteristic makes series resonant circuits especially well suited to be used as basic pass-band filters (acceptors). However, parallel circuits present their maximum impedance at the resonant frequency, which makes them ideal for tuning purposes.
Series resonant circuits have their lowest impedance at the resonant frequency. Parallel resonant circuits have their highest impedance at the resonant frequency. This characteristic is exploited in the design of filters, oscillators and other circuits.
No, the resonant frequency of a RLC series circuit is only dependant on L and C. R will be the impedance of the circuit at resonance.
what is resonant frequency
A parallel resonant circuit has low impedance, when non resonant; however the impedance rises sharply, as the circuit comes to resonance.
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.
To decrease the resonant frequency of any tuned circuit, increase the inductance and/or increase the capacitance.
Resonant in electronics circuit refer to tuning if the resonant condition arise it means the frequency where does the resonant arise is resonant frequency and the gain is highest on that particular frequency. it is widely used in receiver circuits.

1. The RLC series circuit is a very important example of a resonant circuit. It has a minimum of impedance Z=R at the resonant frequency, and the phase angle is equal to zero at resonance.AnswerThe impedance of an RLC circuit is the vector sum of the circuit's resistance, inductive reactance, and capacitive reactance -all of which are expressed in ohms. This applies whether the circuit is at resonance or not.
XL=Xc is the resonance condition for an RLC circuit
A resonator is a circuit that responds to a narrow range of frequencies. A typical resonator is a tuned circuit containing an inductor and a capacitor in series or parallel. A series connected tuned circuit has zero impedance at the resonant frequency, while a parallel tuned circuit has infinite impedance at the resonant frequency. The resonant frequency in both cases depends on the inductance times the capacitance: F = 1 / (2.pi.sqrt(LC)) If the inductance is in Henrys and the capacitance in Farads, the answer is in Hz.
