Question

ALL METERIALS DO NOT ACT AS CONDUCTORS OF ELECTRICITY BECAUSE

Answer 1

Explanation:

Metals are good conductor of electricity because they have very large number of free valance electrons whereas other metals as glass has no free electrons to conduct electricity. So metals good conductor.

Answer 2

Answer:

In conductive materials the outer electrons in each can easily come or go and are called free electrons .In insulating materials the outer electrons are not so free to move. All metals are electrically conductive . Dynamic electricity or electric current is the uniform motion of electrons through a conductor.
