Which outcome occurs when an alternating current frequency exceeds the design limit within an inductor's stray capacitance?

A)Increased core saturation and hysteresis
B)Parallel resonance and impedance spike
C)Decreased eddy current losses in winding
D)Suppressed harmonic distortion in waveform

💡 Explanation

When AC frequency exceeds the design limit, parasitic capacitance within the inductor resonates with its inductance because the inductive and capacitive reactances cancel each other creating a low impedance path, leading to a sharp impedance increase. Therefore parallel resonance results, rather than saturation, decreased losses, or distortion suppression, which require different circuit conditions.
