Aluminum allows for the flow of electrons, while glass does not. Would an aluminum wire surrounded by glass be an effective design for a device that will need to carry an electric current?
A) No, it would not. Both aluminum and glass are conductors, so the current would be exposed to outside elements.
B) No, it would not. Both aluminum and glass are insulators, so the device would not carry a current.
C) Yes, it would. The glass would carry the current, while aluminum is an insulator.
D) Yes, it would. Aluminum is a conductor, and the glass would prevent electricity from transferring to a person holding the device.
