What constitutes a capacitor? CORRECT ANSWER -Two conductors separated by an insulator -In its most basic form the capacitor is constructed of two parallel plates separated by a nonconductor, called a dielectric. (FAA-H-8083-30, Ch. 10) What is the purpose of a capacitor? CORRECT ANSWER -It Stores electrical energy in a electrostatic field. -In an electrical circuit, a capacitor serves as a reservoir or storehouse for electricity. (FAA-H-8083-30, Ch. 10) Does a capacitor in an AC circuit...
