Question

The picture below shows a tester which can be used to identify if an object is a conductor or an insulator. What will happen if we connect the free ends of the wires to an iron rod?

The bulb glows
The bulb does not glow
The bulb bursts
The bulb fuses

hint Hint:

Iron rod is a metal.

The correct answer is: The bulb glows

When an iron rod is connected with the tester, the bulb will glow.

As, iron is a conductor which allows the current to pass through it, therefore, it will complete the circuit and the bulb will glow.
