27 Μαρ 2018 · This book covers Direct Current (DC) circuit theory and is broken up into three modules. Module 1 covers the basics for circuits that include DC sources (voltage or current) and resistors.
Stay tuned, because on the next page we’ll introduce Ohm’s law, which expresses the fundamental relationship between current, voltage, and resistance. Read about Basic DC Circuit Theory (Chapter 1 - Voltage, Current, Energy, and Power) in our free Power Electronics Textbook.
Given simple graphs of current versus power and voltage versus power, determine the value of circuit power for a given current and voltage. Identify the term power, and state three formulas for computing power. Compute circuit and component power in series, parallel, and combination circuits.
It provides clear and concise physics approach to understanding circuit components and the analysis of DC circuits. The physics approach is complemented with excellent explanations and examples of practical devices that go beyond just resistors, capacitors, inductors and dependent sources.
We can take all of the previous Ohm’s Law equations for finding Voltage, Current, Resistance and of course Power, and condense them into a simple Ohms Law pie chart for use in AC and DC circuits and calculations as shown.
This module describes the types of DC motors and includes discussions of speed control, applications, and load characteristics. Volume 3 of 4 Module 7 - Basic AC Theory This module describes the basic concepts of alternating current (AC) electrical circuits and discusses the associated terminology. Module 8 - AC Reactive Components
In general, circuits in which charge flows in one direction are direct current (DC) circuits. In alternating current (AC) circuits (such as those in your house) the current direction continually reverses direction. Despite this difference, many of the concepts addressed in this chapter apply to both DC and AC circuits. Batteries
