Read about Basic DC Circuit Theory (Chapter 1 - Voltage, Current, Energy, and Power) in our free Power Electronics Textbook
DC Voltage and Current flows in one direction and is either positive or negative inrelation to a relatively fixed zero point.The current flow is in one direction only, from Positive to negative (ConventionalCurrent theory)The supply is usually from a Chemical source (Batteries) or a Power ...
Chapter 1Basic AC Theory PDF Version Things start to get complicated when we need to relate two or moreAC voltagesor currents that are out of step with each other. By “out of step,” I mean that the two waveforms are not synchronized: that their peaks and zero points do not match up...
we will perform some “thought experiments” where we lift a 1 kilogram mass 1 meter off the ground and then drop that mass to assess its energy. That 1-kilo mass weighs 9.81 Newtons on Earth, and the distance lifted was 1 meter, so the potential energy stored in the mass is 9.81 jou...
Chapter 1Basic AC Theory PDF Version One of the more fascinating applications of electricity is in the generation of invisible ripples of energy calledradio waves. The limited scope of this lesson on alternating current does not permit full exploration of the concept, some of the basic principles...
Basic Direct Current (DC) Theory PDF Version Pages Two common circuit configurations dominate the landscape of electrical design: the series circuit and the parallel circuit. Most real-world designs include combinations of both models. In addition to Ohm’s Law, we have a set of rules describing...

We use 460V 3ph squirrel-cage motors here, and I need to get up to speed regarding motor basics. I'm a controls guy with a heavy electronics background, well versed in basic ac/dc theory but little motor experience other than the control end. I don't speak calculus.1. Is there a...
