Piezoelectricity is generated by:
- A moving a magnet near a crystal
- B deforming certain crystals
- C touching crystals with magnets
- D adding impurities to a crystal
Correct answer: B — deforming certain crystals. From the official ISED question bank, verified word for word.
Why
Piezoelectricity happens when you squeeze, bend, or twist specific crystals, causing them to generate a small electric voltage. The full explanation — and one for every question — is in Pro.
