What is a benefit of using carbon nanotubes in technology?

1. Low cost

2. High conductivity

3. Biodegradability

4. Low weight

The correct answer is: High conductivity

The selection of high conductivity as a benefit of using carbon nanotubes in technology is accurate due to their remarkable electrical properties. Carbon nanotubes are one of the most conductive materials known, with excellent electron mobility, which allows them to efficiently conduct electricity. This high conductivity enables various applications, particularly in electronics, where they can enhance the performance of components such as transistors, sensors, and flexible electronic devices. In addition to their conductivity, carbon nanotubes also possess other advantageous characteristics such as being lightweight and having exceptional mechanical strength. While they are often touted for their low weight, which is important for applications requiring materials that do not add excessive bulk, the predominant factor driving their use in many high-tech applications is their conductivity. This makes them a cornerstone material in the development of next-generation electronic and energy systems.
