Question
Which of the following is NOT a good conductor of
electricity?Solution
Sulphur is a non-metal and does not conduct electricity because it lacks free electrons. On the other hand, metals like gold, aluminium, and silver are excellent conductors due to the presence of free-moving electrons. Key Points: 1. Metals are good conductors of electricity due to free electrons. 2. Silver is the best conductor of electricity among all metals. 3. Non-metals, including sulphur, are poor conductors due to their electron structure. 4. Gold and silver are also used in electrical components for high efficiency. 5. Aluminium is lightweight and widely used in electrical wiring. Bee Facts: • Gold (a): Excellent conductor, highly resistant to corrosion. • Aluminium (b): Good conductor, cheaper than copper. • Sulphur (c): Poor conductor, non-metal. • Silver (d): Best conductor of electricity.
