Extra exam question E6D03
Subelement E6, CIRCUIT COMPONENTS· Group E6D
Which of the following is an aspect of the piezoelectric effect?
- A.Mechanical deformation of material due to the application of a voltage (correct answer)
- B.Mechanical deformation of material due to the application of a magnetic field
- C.Generation of electrical energy in the presence of light
- D.Increased conductivity in the presence of light
WhyThe piezoelectric effect includes mechanical deformation of a material due to the application of a voltage. The piezoelectric effect includes the mechanical deformation, a physical flexing or dimensional change, that certain crystalline materials undergo when a voltage is applied across them, the converse of the same materials generating a voltage when physically stressed, answer A. Magnetic-field-driven deformation, light-driven electrical generation, and light-driven conductivity changes are all separate physical effects unrelated to piezoelectricity.
