← ScienceWhich outcome occurs when excessive electromagnetic interference affects capacitance measurements in a high-precision sensor?
A)Spurious harmonics distort the signal✓
B)Increased device power consumption occurs
C)The temperature drifts out of bounds
D)Materials experience accelerated ionic diffusion
💡 Explanation
Spurious harmonics distort the signal because electromagnetic interference modulates the resonant frequency of the capacitor, disrupting capacitance measurements via frequency mixing; therefore harmonics appear, rather than simple baseline shifts or unrelated effects such as power increase induced via resistance.
