Question

The output of a piezoelectric crystal has
1. low amplitude and low impedance
2. high amplitude and high impedance
3. low amplitude and high impedance
4. high amplitude and low impedance

Answer 1

Correct Answer - Option 3 : low amplitude and high impedance

Piezoelectric Transducer:

• It is an electrical transducer that can convert any form of physical quantity into an electrical signal, which can be used for measurement.
• Crystals made from quartz took are used as a primary material for piezoelectric crystal transducers. These crystalline materials exhibit the property of piezoelectricity, according to which, on the application of any type of mechanical stress or strain it leads to the generation of an electric voltage proportional to the applied stress.
• The output of a piezoelectric crystal has low amplitude and high impedance.
