Lead
Paper
Rubber
None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: C. Rubber
Rubber is a good insulator because it is a poor conductor of electricity. It is also flexible and can be easily molded into different shapes, making it ideal for use in high voltage cables.
Lead is a poor conductor of electricity, but it is also a heavy metal that can be toxic if it is ingested. Paper is a good insulator, but it is not as flexible as rubber and can be damaged by moisture. None of the above is the correct answer because none of the other options are commonly used for insulation in high voltage cables.
Here are some additional details about each option:
- Lead is a poor conductor of electricity, but it is also a heavy metal that can be toxic if it is ingested. Lead was once commonly used for insulation in high voltage cables, but it has been largely replaced by other materials due to its toxicity.
- Paper is a good insulator, but it is not as flexible as rubber and can be damaged by moisture. Paper was once commonly used for insulation in low voltage cables, but it has been largely replaced by other materials due to its lack of flexibility and its susceptibility to moisture damage.
- Rubber is a good insulator because it is a poor conductor of electricity. It is also flexible and can be easily molded into different shapes, making it ideal for use in high voltage cables. Rubber is the most common material used for insulation in high voltage cables.
