Which of the following is an aspect of the piezoelectric effect?
The correct answer is A: Mechanical deformation of material due to the application of a voltage. Which of the following is an aspect of the piezoelectric effect is mechanical deformation of material due to the application of a voltage. Piezoelectric materials deform when voltage is applied. For amateur radio operators, this is important for component knowledge. Understanding this helps when working with crystals.
Exam Tip
Aspect of piezoelectric effect = mechanical deformation due to application of voltage. Think 'P'iezoelectric 'E'ffect = 'P'ressure from 'E'lectricity (voltage causes deformation). Piezoelectric materials deform when voltage is applied. Not magnetic field, not light (photovoltaic), not light conductivity - just voltage causes deformation.
Memory Aid
"Aspect of piezoelectric effect = mechanical deformation due to application of voltage. Think 'P'iezoelectric = 'V'oltage causes 'D'eformation. Piezoelectric materials deform when voltage is applied. Important for component knowledge."
Real-World Application
An aspect of the piezoelectric effect: It's mechanical deformation of material due to the application of a voltage. When voltage is applied to a piezoelectric material, it physically deforms. This is an aspect - voltage causes mechanical deformation.
Key Concepts
Why Other Options Are Wrong
Option B: Incorrect. Mechanical deformation due to magnetic field isn't piezoelectric - piezoelectric is due to voltage. Magnetic field isn't piezoelectric.
Option C: Incorrect. Generation of electrical energy in presence of light isn't piezoelectric - that's photovoltaic. Light isn't piezoelectric.
Option D: Incorrect. Increased conductivity in presence of light isn't piezoelectric - that's photoconductivity. Light conductivity isn't piezoelectric.
