1 What is a basic advantage of using AC for electrical power for a large aircraft?

A. AC systems operate at higher voltage than DC systems and therefore use less current and can use smaller and lighter weight wiring. B. AC systems operate at lower voltage than DC systems and therefore use less current and can use smaller and lighter weight wiring. C. AC systems operate at higher voltage than DC systems and therefore use more current and can use smaller and lighter weight wiring.
