Using the "conduction tester" on an object it is found that the bulb begins to glow. Is that object a conductor or an insulator? Explain.

Open in App

Solution

If the object is a good conductor of electricity then current will pass through the conduction tester and the bulb will glow because a conductor of electricity is a material which allows an electric current to flow through it. Now it is given that the bulb begins to glow when the conduction tester is used on the object. Hence, the object is a good conductor of electricity.
