piezoelectric crystals can be used in printers. during printing, an electric current is applied to the piezoelectric crystal that causes the crystal to produce a force and push ink out of the printer and onto paper. explain how the electric current affects the charged atoms in the piezoelectric crystal and how this causes the crystal to change size and push ink out of the printer. enter your answer in the box provided.
Answer
Brief Explanations:
Piezoelectric crystals have a unique property. When an electric - current is applied, the electric field interacts with the charged atoms (ions) in the crystal lattice. This interaction causes the ions to re - arrange. The re - arrangement of ions leads to a change in the inter - atomic distances and angles within the crystal structure. As a result, the crystal deforms or changes size. This mechanical deformation generates a force that can push ink out of the printer onto the paper.
Answer:
When an electric current is applied to a piezoelectric crystal, the electric field affects the charged atoms (ions) in the crystal lattice, causing them to re - arrange. This re - arrangement leads to a change in the crystal's size due to the alteration of inter - atomic distances and angles. The resulting mechanical deformation generates a force that pushes ink out of the printer onto the paper.
