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 are acceptor circuits?

A series RLC circuit when powerd by an AC source of frequeny equal to its resonant frequency is an 'acceptor circuit'

Why is the RLC series circuit called 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.

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.

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.
