Final answer:
The resonant frequency of an AC circuit, determined by the circuit's inductance and capacitance, is independent of the peak voltage of the AC source. It is a property of the circuit elements rather than the input voltage.
Step-by-step explanation:
The resonant frequency of an AC circuit is the frequency at which the inductive reactance and capacitive reactance are equal and cancel each other out, leading to a scenario where only the resistance determines the impedance. The resonant frequency (denoted as fo) is calculated by the formula fo = 1 / (2π√(LC)), where L is the inductance and C is the capacitance. Therefore, the resonant frequency is independent of the peak voltage of the AC source and only depends on the values of L and C in the circuit.
In RLC series AC circuits, factors like resistance can affect the quality factor and the sharpness of the resonant peak, but not the actual resonant frequency itself. Changing the peak voltage might change the amplitude of current or voltage at resonance, but it does not shift the resonant frequency. To conclude, the correct answer is: b) No, the resonant frequency is independent of peak voltage.
