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.
A series RLC circuit when powerd by an AC source of frequeny equal to its resonant frequency is an 'acceptor circuit'
The series RLC circuit exhibits minimum resistance at resonance. This means an input at the resonant frequency will see maximum current in that RLC circuit. Put another way, the RLC circuit is said to accept the current of an input signal when that signal equals the resonant frequency of the RLC circuit.
reactance approaches zero at resonance
if resonant ckts r connected serially, it is called serial resonant ckt.. if resonant ckts r connected parallely, it is called parallel resonant ckt..
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.
series resonant circuit
A series resonant circuit exhibits minimum impedance when on tune. A parallel resonant circuit exhibits maximum impedance when on tune.
series resonant is voltage magnification whereas parallel resonant is current magnification type of circuit.
To decrease the resonant frequency of any tuned circuit, increase the inductance and/or increase the capacitance.
A series resonant circuit has it's reactive components connected in series with each other; while the reactive components, as in a "tank" circuit, are connected in parallel with each other. The resonant series circuit has the capability of producing usable increased voltage levels across each component at resonance, while the resonant tank circuit does not. The resonant parallel, or "tank" circuit; has the dual capability of creating a situation whereby the input amperage level is reduced to minimum while, at the same time, a maximum amount of circulating amperage is created between the two reactive tank components at resonance.
Answer:A given combination of R,L and C in series allows the current to flow in a certain frequency range only.For this reason it is known as an acceptor circuit i.e.,it accepts some specific frequencies....
Series resonance occurs when a circuit's inductive reactance is equal to its capacitive reactance. The resistance of the circuit is irrelevant.WebRep currentVote noRating noWeight
What is meant by resonance and explain the series and parallel resonance? by kathiresan
because in LCR parallel circuit xl=xc=0 and hence it allows AC currents to circulate through it easily.
Acceptor circuit are series circuit in which indactor and capacitor are join in series there is single path available for flow of current.while in rejector circuit inductor and capacitor are join in parallel more then one path are available for flow of current .

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.
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.
At resonant frequency, current in the circuit is maximum.Impedence is minimum.
just like it soundsseries resonant has capacitor & inductor in seriesparallel resonant has capacitor & inductor in parallel
They are usually just called that - "series circuit".
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.
It is called a series circuit.
Series CircuitWe say Resistances are in series if the same current flows through all Resistances. A circuit containing of only series resistances is called a series circuit. A series circuit is a circuit that has the same intensity of current flow through its elements.
