← ScienceWhich outcome occurs when a dielectric material with high permittivity gets mechanically stressed inside a capacitor?
A)Increased voltage breakdown risk
B)Decreased capacitance stability✓
C)Elevated equivalent series resistance
D)Enhanced charge storage capability
💡 Explanation
When a high permittivity dielectric is stressed, piezoelectricity occurs via deformation-induced polarization changes, this alters the dielectric constant and thus shifts the precise capacitance because geometric factors and material properties determine overall capacitance. Decreased capacitance stability is the result, rather than breakdown, higher resitance, or enhanced storage, as each of those requires totally independent mechanisms and conditions.
