DC Power Supplies Fundamental Concepts
...ower supply, typically connected to a house or office AC (alternating current) wall outlet. These include radios, stereo systems, TV, computers, and other devices which we use daily. The discussion starts with the primary power source - the wall socket, and a brief history about AC power. Several basic power supply configurations are described to support the functional concepts introduced.

Alternating Current Fundamentals
...o flow in the other coil (the "secondary"). The alternating current that flows through the primary winding establishes a time-varying magnetic flux, some of which links to the secondary winding and induces a voltage across it. The number of times the wires are wrapped around the core ("turns") is very important and determines how the transformer changes the voltage.

A Unique and Understandable Way to Look at Three Phase Circuits
...hat in mind, this course starts by reviewing single phase alternating current circuits including resistive, capacitive, and inductive circuits. This is a quick review emphasizing voltage, current, and power relationships in these three common circuit elements. Waveforms and their relationship to vectors is shown. Then most three phase circuits are shown to be nothing more than a number of

Reactance in AC Circuits - Fundamental Concepts
...Reactance is the measure of the opposition to the flow of alternating current caused by the inductance and capacitance in a circuit rather than by resistance. Steady electric currents flowing along conductors in one direction undergo opposition called electrical resistance, but no reactance. Reactance is present in addition to resistance when conductors carry alternating current. Reactance also
