Which consequence results when high voltage application causes dielectric breakdown in ionic ceramics?

A)Formation of conductive filament paths
B)Creation of electron-hole pairs
C)Increased piezoelectric coefficient
D)Enhanced Raman scattering intensity

💡 Explanation

Electrical arcing causes conductive filaments to form through **electrochemical migration**. Ion mobility increases locally because of intense electrode field gradients. Therefore a short circuit forms, rather than increased carrier concentration or enhanced optic/piezo effects which require intact lattices.
