Piezo crystals

What happens when certain crystals like quartz are stressed?

• They melt.

• They produce an electrical potential.

• They become magnetic.

• They change color.

What is the nature of the process involving electrical potential and mechanical stress?

• It is reversible.

• It is irreversible.

• It is unpredictable.

• It is constant.

What effect does a potential difference have on a crystal?

• It cools the crystal.

• It makes the crystal heavier.

• It distorts the crystal.

• It changes the crystal's color.

Where is the principle of electrical energy from mechanical stress used?

• In wind turbines.

• In pressure sensors of electronic fuel injection systems.

• In solar panels.

• In batteries.

What is one application of the principle discussed in the video?

• Measuring temperature.

• Generating wind energy.

• Storing solar energy.

• Detecting pressure changes in fuel systems.
