Question

Write a detailed note on Piezo-electric effect and Quartz crystal.
​

Answer 1

Answer:

Piezoelectricity is the electric charge that accumulates in certain solid materials in response to applied mechanical stress.

Piezoelectricity is the process of using crystals to convert mechanical energy into electrical energy, or vice versa. Regular crystals are defined by their organized and repeating structure of atoms that are held together by bonds, this is called a unit cell.

There are many forms of quartz that exist apart from the crystals used for electronics resonators. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.
