Q.8 Using the“conduction tester” on an object it was found that the bulb begins to glow. Is that object a conductor or an insulator? Explain.


Answer :

(1) The object is a conductor because the bulb glows only when the conductor is used but not when the insulator is used.

(2) As conductor allows the electric current to pass through it and causes the bulb of the tester to glow.
