Question

Which statement is accurate about the impedance of a series RLC circuit at the resonant frequency?

c) The impedance of a series RLC circuit is maximum in magnitude at the resonant frequency and is equal to the resistance.

a) The impedance of a series RLC circuit is maximum in magnitude at the resonant frequency and is equal to the sum of the resistance and reactance. b) The impedance of a series RLC circuit is minimum in magnitude at the resonant frequency and is equal to the sum of the resistance and reactance.

c) The impedance of a series RLC circuit is maximum in magnitude at the resonant frequency and is equal to the resistance.

d) The impedance of a series RLC circuit is minimum in magnitude at the resonant frequency and is equal to the resistance.

Explanation / Answer

Answer: D.The impedance of a series RLC Circuit is minimum in magnitude at the resonant frequency and is equal to the resistance.

Reason: impedance is minimum at resonance simply to resistance R and equal to the resistance.Impedance of series RLC circuit during resonance condition known as "Dynamic impedance" often based on frequency.
