What is exhibited when an ac voltage placed across a crystal causes it to vibrate at the frequency of the applied voltage?
A) a modulating signal
B) a fundamental frequency
C) a harmonic frequency
D) the piezoelectric effect

Question

Quizplus · Accepted Answer

The piezoelectric effect is exhibited when an AC voltage is applied to a crystal causing it to vibrate at the frequency of the applied voltage. This effect is used in various applications such as sensors, filters, and oscillators. A modulating signal, fundamental frequency, and harmonic frequency are not specifically related to the piezoelectric effect.
