Which of the following is NOT a good conductor of electricity?

Correct option is B

The correct answer is (b) Sulphur

• Sulphur is a non-metal and is a poor conductor of electricity.

• It does not have free electrons or mobile ions that allow the flow of electric current.

• On the other hand, Gold, Silver, and Aluminium are metals and have free-moving electrons in their atomic structure, making them excellent conductors.

• Silver is the best conductor of electricity, followed by copper, gold, and aluminium.

Information Booster:

• Silver: Best electrical conductor, used in high-precision electronics.

• Gold: Highly conductive and corrosion-resistant, used in connectors and circuits.

• Aluminium: Lightweight, cost-effective conductor used in transmission lines.

• Sulphur: Non-metal, used in insulators and chemicals, does not conduct electricity.

Additional Information:

• Conductors: Allow electric current to pass (e.g., metals like Cu, Ag, Al).

• Insulators: Do not allow electric current (e.g., wood, rubber, sulphur).

• Conductivity depends on the presence of free electrons or ions.

• Sulphur is used in the manufacture of rubber, fertilizers, and sulfuric acid, but not in electrical applications.
