The piezoelectric effect in a crystal is___________?
Correct answer: A. A voltage developed because of mechanical stress
- A. A voltage developed because of mechanical stress
- B. A change in resistance because of temperature
- C. A change in frequency because of temperature
- D. None of the above
Explanation
The piezoelectric effect produces an electric voltage when a crystal is mechanically stressed, and the reverse effect produces mechanical deformation from an applied voltage. Temperature-dependent frequency change is a separate crystal property.
