Question -

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 -

The material of that object is a conductor. Because with this object bulb lights up showing that electricity is flowing in the circuit, i.e., the circuit is complete. This is possible only if the material of the object allows the electricity to pass through it and we know only conductors allow the electricity to pass, thus the material of the object must be a conductor.
