Electrostatic induction

  1. Sep 11, 2014 #1
    Do electrostatic fields induce charges on conductor surfaces faster than dielectrics respond to an identical field?

    Conduction electrons adjust in femtoseconds or less; I suspect that dielectrics respond slightly slower.

    You cannot detect the difference by electronic means; it would require optical experiments.

    Thanks Ultrafast. Am I correct in assuming that if a conductor is cooled, it will react faster to electrostatic fields?

    If a field is changing (which is necessary to reveal any delay), it is no longer 'static'. The term is just 'electric field'.
