Because the only opposition to current flow is the resistance of the circuit. This is because, at resonance, the vector sum of the inductive and capacitive reactances is zero.

Why LCR series circuit is called acceptor circuit?
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....
What is meant by resonance in LCR circuit?
a circuit in which inductance L,capacitance C and resistance R are connected in series and the circuit admits maximumum current corresponding to a given frequency of a.c.Another AnswerIn the case of a series circuit, resonance occurs when its inductive reactance is exactly equal to its capacitive reactance. As the vector sum of these two quantities will then be zero, the only opposition to current will be resistance and, so, maximum current will flow through the circuit when resonance occurs. ALL circuits can be made to resonate at what is called their 'resonant frequency' because, as frequency increases, the inductive reactance increases but capacitive reactance falls -so, at some point the two will equal each other, and resonance will occur.In my view resonance means - the condition that exists when the inductive reactance and the capacitive reactance are of equal magnitude, causing electrical energy to oscillate between the magnetic field of the inductor and the electric field of the capacitor.
How does series resonance differ from parallal resonance?
In series resonance, the inductance and the capacitance are connected in series, but in parallel resonance they are connected in parallel. In series resonance, at an input signal with a frequency equal to resonance frequency, the total impedance of both inductive and capacitive elements together is zero (or they appear as short circuits) unlike the parallel resonance case in which it is infinite and they appear as an open circuit.
Why does a series resonant circuit cannot be tank circuit?
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.
Does resonant frequency of RLC series circuit depends on Resistance?
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.

Resonance in an L-C-R AC Series circuit experiment?
At resonant frequency, current in the circuit is maximum.Impedence is minimum.
In a series RLC circuit at frequencies above resonance is the circuit capacitive or inductive?
in series you XL, voltage leads the current, and in Parallel current leads the voltage. so your answer should reflect on this theory.
Series resonance circuit is also known as acceptor circuit why?
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.

What happens in series resonance?
The properties of a series alternating-current L-R-C circuit at resonance are:the only opposition to current flow is resistance of the circuitthe current flowing through the circuit is maximumthe voltage across the resistive component of the circuit is equal to the supply voltagethe individual voltages across the inductive and capacitive components of the circuit are equal, but act in the opposite sense to each otherthe voltage appearing across both the inductive and capacitive components of the circuit is zeroif the resistance is low, then the individual voltages appearing across the inductive and capacitive components of the circuit may be significantly higher than the supply voltage
Why does series rlc circuit provides voltage magnification at resonance?
IN A SERIES RLC CIRCUIT XL=XC.THEREFORE, IMPEDANCE Z IS MINIMUM AND Z=R.SINCE THE IMPEDANCE IS MINIMUM,CURRENT IN THE CIRCUIT WILL BE MAXIMUM. XL=XC MULTIPLYING BY MAX. CURRENT Io (AT RESONANCE) ON BOTH SIDES, WE GET, IoXL=IoXC I.E. Vlo=Vlc(POTENTIAL DIFFERENCE ACROSS INDUCTANCE IS EQUAL TO THE POTENTIAL DIFFERENCE ACROSS CAPACITANCE AND BEING EQUAL AND OPPOSITE THEY CANCEL EACH OTHER.)SINCE Io IS MAXIMUM,Vlo AND Vco WILL ALSO BE MAXIMUM.THUS,VOLTAGE MAGNIFICATION TAKES PLACE DURING RESONANCE.HENCE,IT IS ALSO REFERRED TO AS VOLTAGE MAGNIFICATION CIRCUIT.

Derive the bandwidth expression of frequency modulation wave?
A resistor&capacitor are in series with a variable inductor.When the circuit is connected to 200v,50Hz supply,the maximum current obtained by varying the inductance is 0.314A.The voltage across capacitor,when the current in circuit is maximum is 800v.Choose the values of series circuit elements?

Why series resonance is called voltage resonance?
Series resonance isn't generally referred to as 'voltage resonance', but the expression probably comes from the fact that, at resonance, the voltage drop across the inductive component of a circuit is exactly equal to the voltage drop across the capacitive component of the circuit and, if the resistance of the resonant circuit is low in comparison with its reactance, then each of these voltage drops can be significantly higher than the supply voltage.
