Piezoelectric Effect:-

  • When a mechanical compression or tension is applied to some crystals like quartz, a potential difference is developed across the crystal which is proportional to the applied pressure. This phenomenon is known as Piezo-electric Effect.

  • Also if the potential difference is applied across the crystal, a mechanical compression …
