Question 1 Report
This figure shows a nanotube-like carbon structure being tested as a possible lightweight wire in a drone. The carbon atoms form a long hollow network. Engineers need a material that has low mass but can carry current from the battery to a motor. Copper wire works well, but increases the drone's mass.
(a) Name the element that makes up the structure. [1]
(b) Give one advantage of using a lightweight wire in a drone. [1]
(c) Suggest why this carbon structure may conduct electricity. [2]
Answer Details
The nanotube-like structure is a carbon material being considered as a lightweight conducting wire.
- (a) The element is carbon. [1]
- (b) A lightweight wire means less energy or fuel is needed to move the drone. It could also allow a greater payload. [1]
- (c) The carbon structure may have delocalised, or free, electrons. These electrons can move through the structure and carry electrical charge, so it can conduct. [2]
