← ScienceWhich outcome occurs when a high voltage is applied across a dielectric material with weak intermolecular forces?
A)Dielectric breakdown due to ionisation✓
B)Magnetic saturation from aligned dipoles
C)Thermal expansion due to increased polarization
D)Increased resistivity from carrier depletion
💡 Explanation
When a high voltage is applied, dielectric breakdown occurs due to impact ionization, exceeding the dielectric strength and causing a chain reaction of electron-ion pair generation that lead to a sudden drop in resistance. Therefore dielectric breakdown occurs, rather than magnetic saturation, thermal expansion, or increased resistivity, which involve different responses to electric fields at lower intensities.
