Introduction to Capacitance
...o store an electric charge. An electronic device called a capacitor is designed to provide capacitance in an electric circuit by providing a means for storing energy in an electric field between two conducting bodies. A capacitor in its simplest form consists of two conducting plates separated by an insulating layer called a dielectric. When a capacitor is connected in a circuit across a

Reactance in AC Circuits - Fundamental Concepts
...idly the applied voltage changes in value, the faster the capacitor stores energy. This means that a high-frequency alternating voltage will put more current into a given capacitor than a low frequency voltage could. Thus the reactance of a capacitor goes down as the frequency increases. Reactance produces a phase shift between the electric current and voltage in the circuit. Reactance is

Alternating Current Motors and Generators
...asonable level. Types of motor starting include reactive (capacitor start and inductive start), and electronic (frequency drives and soft start drives). The reactive start method is usually used on fractional horsepower motors, and the electronic method is usually reserved for larger motors. This 4-hr course provides a basic understanding of AC motors and generators, explaining how to use

First Order RLC Circuits Time Domain Analysis
...using discreet passive (R) resistor, (L) inductor and (C) capacitor components. The complete response for each of the 4 basic circuits has transient and steady state terms. The sum of the transient and steady state terms comprises the complete response of the circuit. Once we have the complete response of a circuit we can alter the circuit element values to our specifications and plot the
