Question

Using the “conduction tester” on an object it was found that the bulb begins to glow. Is that object conductors or insulator. Explain.

Answer 1

Because with this object the bulb begins to glow showing that the electric current is flowing in the circuit i.e. The electric circuit is complete. This can be possible only when the material of the object allows the current to flow through it and we know that only conductors allow current to flow through them. Therefore, the object is a conductor.
