Question

Which of the following materials is preferably used for electrical transmission lines?

• A. Nichrome
• B. Tin-lead alloy
• C. Copper
• D. Tungsten

Answer 1

Answer:

C. Copper

• Copper wire can be used for electrical transmission lines because being of low resistance it is a good conductor of electricity.

• This inherent property makes copper an excellent conductor of electricity, allowing for efficient and minimal energy loss during the transmission of electrical power over distances.

• Its combination of good conductivity and reasonable cost makes it a practical and widely used material in electrical infrastructure.
