← ScienceWhich outcome occurs when a dielectric material fills a radio-frequency inductor's magnetic field?
A)Resonant frequency significantly decreases✓
B)Quality factor significantly increases
C)Inductance value remains nearly constant
D)Saturation current threshold immediately lowers
💡 Explanation
Resonant frequency decreases because the inserted higher permittivity dielectric enhances the inductor's effective capacitance via increased electric **polarization**. This lowers the resonant frequency because frequency is inversely proportional to capacitance; therefore, resonance drops rather than inductance changing significantly.
