_________ is an example of piezoelectric material?
Correct answer: B. Quartz
- A. Glass
- B. Quartz
- C. Corrundum
- D. Neoprene
Explanation
Quartz is a classic piezoelectric material: mechanical stress on it produces charge, and an applied voltage causes mechanical deformation. Glass, corundum, and neoprene are not the standard example intended here.
