What constitutes a capacitor? -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? -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 cause the current to le...

1) An ac source of period T and maximum voltage V is connected to a single unknown ideal element that is either a resistor, and inductor, or a capacitor. At time t = 0 the voltage is zero. At time t = T/4 the current in the unknown element is equal to zero, and at time t = T/2 the current is I = -Imax, where Imax is the current amplitude. What is the unknown element? A) a resistor B) an inductor C) a capacitor D) an inductor or a capacitor Answer: C 2) When an LRC series circuit is driven at...
