It hardly conducts any electricity at all, so we can say it’s an electrical insulator. Inside the plastic ... graphite is an example of a non-metal which is a good electrical conductor.

It is difficult to reconcile these observations with a transcriptional insulator model. For example, a reasonable prediction from the decoy model is that two insulators would be better than one.

The rubber around this wire is an insulator. Some materials do not allow electricity to pass through them. These materials are known as electrical insulators. Make a list of all of the objects ...
