is 900kv/mm considered a conductor or semiconductor??

Question

it is a proposed Dielectric strength of a plastic... I apologize for the confusion, I want to know if this is even possible

Answer 1

Any (known) material exposed to that kind of electric field will conduct, and therefore is a conductor.

If you could develop an insulator that could withstand that kind of electric field, then you would become very wealthy.

Answer 2

The question makes no sense. An electric field of 900 kv/mm is HUGE, and cannot be sustained by any conductor without instant vaporization.

Answer 3

Rethink your question
