Question
In piezoelectric transducer, the polarity of produced charge depends upon.
- Transducer orientation
- Piezoelectric material property
- The direction of applied stress
- All the above
Hint:
The piezoelectric effect is caused by applying mechanical stress to generate electrical energy.
The correct answer is: The direction of applied stress
In the piezoelectric transducers, the polarity of the charge depends on the direction of the stress applied.
- The piezoelectric effect is caused by applying mechanical stress to generate electrical energy.
- The materials used to generate the mechanical stress are piezoelectric transducers.
- The polarity of the charge depends on the direction of the applied mechanical stress.
