Question
Piezoelectric effect is when materials produce electric charges when:
- Voltage is applied
- Mechanical stress is applied
- Electric field is applied
- Magnetic field is applied
Hint:
When pressure or force is applied to a certain material, the piezoelectric effect takes place. Whenever a force or pressure is applied to the material, it vibrates.
When crystals are compressed, stretched, or twisted, for instance, they become polarised and produce voltage after being polarised.
The correct answer is: Mechanical stress is applied
The materials produce electrical charges when mechanical stress is applied in the piezoelectric effect.
- The piezoelectric effect is the production of electric charges from solid materials.
- The electric charges are generated due to the mechanical stress applied to the materials.
- The materials used to produce the piezoelectric effect are called transducers.
