Identify the term power, and state three formulas for computing power. Compute circuit and component power in series, parallel, and combination circuits. Compute the efficiency of an electrical device. Solve for unknown quantities of resistance, current, and voltage in a series circuit.
This module describes the basic concepts of direct current (DC) electrical circuits and discusses the associated terminology. Volume 2 of 4 Module 3 - DC Circuits This module introduces the rules associated with the reactive components of inductance and capacitance and how they affect DC circuits. Module 4 - Batteries
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.
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.

10.1 - Practical Circuits. Batteries have an internal resistance (r) which is caused by electrons colliding with atoms inside the battery, as this results in some energy being lost before electrons even leave the battery. It is represented as a small resistor inside the battery.
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
