Question

write to show that electric is a insulator?​

Answer 1

Answer:

By placing the object or material in the path of electric current . Explanation:If the object or the material conducts electricity the bulb will glow and the object is a conductor. If the object or the material doesn't conducts electricity the bulb will not glow and the object is an insulator.

Explanation: These materials work by tightly binding electrons so there is no electron flow between them and therefore no conduction. Electrical insulators may be used for circuit boards, high voltage systems and as coating on electric wire and cable.

Some materials such as glass, paper and Teflon, which have high resistivity, are very good electrical insulators.
