Exam 12: Conductors and Insulators

Insulators maintain a charge because electrons cannot flow to neutralize the charge and are commonly called

A component that allows us to control whether the current is on or off in a circuit is a

A conductor is any material that resists or prevents the flow of electric charge, such as electrons.

The advantage of a circuit breaker is that it can be ______________ once the bimetallic strip cools down and the short circuit has been removed.

In typical applications, hook-up wire for electronic circuits in the order of milliamperes is generally about No. 2.

For applications in heating elements, what type wire should be used?

Most electronic circuits are mounted on a plastic or fiberglass insulating board with printed wiring that is called a
