Electrical Engineering XYZ MCQs
Piezoelectric effect is carried out in:
- M derived
- Composite filter
- Constant k prototype
- Crystal filter
Correct answer: 4. Crystal filter
Explanation: The piezoelectric effect is a phenomenon where certain materials generate an electric charge in response to mechanical stress or deformation. Conversely, when an electric field is applied to these materials, they undergo mechanical deformation. This effect is utilized in various applications, including sensors, actuators, and filters.
