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 a gold bar?
- The bulb glows
- The bulb does not glow
- The bulb bursts
- The bulb fuses
Hint:
Gold is a conductor.
The correct answer is: The bulb glows
- Gold bar is the metal that is a good conductor of electricity.
- When the gold bar is connected to both ends of the wires, being the conductor, the gold bar will conduct the electricity.
- Thus, as a result, the bulb will glow.
