Which outcome arises when applying a high electric field to an ionic crystal near its dielectric breakdown strength?

💡 Explanation

When a high electric field is applied to an ionic crystal, increased ionic conductivity occurs because the increased field lowers the activation energy required for ions to hop between lattice sites, leading to increased ion movement. Therefore, hopping conductivity dominates, rather than decreased mobility, reversal, or superconductivity which require alternative mechanisms.
