← ScienceWhich outcome arises when compressive stress distorts a quartz crystal?
A)Voltage differential via piezoelectricity✓
B)Spontaneous current from thermoelectricity
C)Increased band gap via piezoresistance
D)Reduced magnetism through magnetostriction
💡 Explanation
Voltage arises because compressive stress induces charge separation via the piezoelectric effect. Therefore a voltage differential occurs, rather than thermoelectric current generation or alteration of either the band gap or magnetic properties, because those use a thermal or magnetic trigger.
