Which of the following is a common conductor used in electrical wiring?

• A. Gold
• B. Silicon
• C. Copper
• D. Carbon

Answer: (C)

Copper is a common conductor used in electrical wiring due to its excellent electrical conductivity, durability, and resistance to corrosion. It allows for efficient transmission of electricity with minimal energy loss, making it ideal for residential and commercial electrical systems. Copper's malleability also makes it easy to work with during installation, allowing it to be drawn into wires of various sizes and shapes. While gold is also an excellent conductor, it is rarely used in general electrical wiring due to its high cost. Silicon, on the other hand, is primarily a semiconductor, which means it conducts electricity under certain conditions but not as effectively as a true conductor like copper. Carbon, although it can conduct electricity, does not have the same level of conductivity or practical application in wiring as copper. Therefore, copper remains the most widely used material for electrical wiring.
