Can Electric Fields Pass Through Both Conductors and Insulators?

[Godwin Kessy]

Do both conductors and insulators allow electric fields through and why?

No, conductors block EM waves. That is the principle behind a Faraday cage.

hey! Isnt that all about faradays cage is the principle under gaussians law, and by the way why conductors don't allow electric field pass through as the insulators do?

The electrons in a conductor are free to move. If there were an electric field, the electrons would accelerate. The only way for a conductor to be at equilibrium is for the electric field to be 0.

Thanks man!
