CBSE · Class 12 · Physics · Electric Charges and FieldsThe dielectric constant ($K$) of a perfect metallic conductor is:
Step-by-Step Solution
For a perfect conductor/metal, electric field inside is zero, making charges move freely to neutralize any external field. Hence, its dielectric constant $K = \infty$ (infinity).
