At zero frequency, the current is zero since there is a nonconductor between the plates. |
On this point he remarks that the evil effects of the scale are due to the fact that it is relatively a nonconductor of heat. |
Strictly speaking, all substances conduct electricity in some degree, and a nonconductor is merely a bad conductor. |
Warning: The cover must consist of a nonconductor, otherwise the radio signals are blocked and the receiver cannot detect the transmitter's information. |
Paper can be so treated that it will either conduct electricity or become a nonconductor, as may be desired. |
All you have to do is wrap your core with a nonconductor, say nylon thread, and presto, nothing comes out. |
