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.

In 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.
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 parameter stay the same in LCR circuit ?
XL=XC
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.
It uses Impedance technique. Check Out some LCR meter data sheets such as Agilent user manual it has a break down on the measurement principles or search for books on instrumentation and measurement which explain the actual circuit diagram.

what parameter stay the same in LCR circuit ?
For a particular frequency if the current or the voltage of the circuit is Maximum or Minimum then that circuit is said to be in resonance .
oppose changes in current flow.
XL=Xc is the resonance condition for an RLC circuit
XL=XC
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.
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.
