← ScienceWhich consequence results when dielectric aging reduces capacitance?
A)Oscillator frequency drifts unpredictably upwards✓
B)Amplifier gain becomes severely unstable
C)Filter cutoff frequency rises unexpectedly
D)Energy consumption unexpectedly decreases drastically
💡 Explanation
The oscillator's Colpitts configuration uses capacitance to set frequency; dielectric degradation modifies capacitance. Capacitive reactance increases because of dielectric aging, increasing frequency through the frequency oscillation formula. Therefore the frequency shifts upwards rather than decreasing, due to this mechanism.
