← ScienceWhich consequence results when parasitic capacitance bridges an RF inductor?
A)Resonance frequency shifts lower✓
B)Inductance value increases linearly
C)Core saturation occurs rapidly
D)ESR decreases exponentially
💡 Explanation
The parallel parasitic capacitance creates a parallel LC resonant circuit; the added C results in a lower resonant frequency because the resonance decreases with increased capacitance. Therefore, self-resonance occurs at a lower frequency, rather than higher due to inductance effects limiting total impedance.
