Electrical Fundamentals

1. An aircraft company has decided to replace the copper cables to the main aircraft generators onboard it's Boeing 747s with aluminium cables that are capable of carrying the same current.

a. Describe the effects on the cable with the aircraft at sea level compared to 35,000 feet. Like coefficient of expansion at sea level and on 35,000 feet, resistivity.

2. A parallel plate capacitor was originally constructed using air as the dielectric. For another application, we need to change the dielectric to Mica.

a. Describe fully how this change of dielectric material has affected the capacitor in ALL respects.
