← ScienceWhich conduction impact occurs when applying stress causes dislocations within a crystal lattice?
A)Increased electrical resistivity results downstream✓
B)Reduced thermal expansion coefficient measured
C)Amplified piezoelectric voltage generation
D)Reversed thermoelectric current direction
💡 Explanation
Deformation introduces imperfections, and thus dislocation scattering contributes to increased resistivity because it impedes electron flow within the lattice structure. Therefore, electrical resistivity increases, rather than changes to expansion, voltage output, or thermoelectric behavior, which depend upon separate mechanisms.
