Chapter 1 - Voltage, Current, Energy, and Power. Voltage and Current Relationship. The earth is a dynamic place. Objects are moving, chemical reactions are taking place, temperatures are increasing and decreasing. This abundance of perpetual activity is bound to the concept of energy.
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.
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
CHAPTER. The objective of analysing a particular circuit is to determine the various responses of current, voltage, etc., which are produced in the circuit due to the presence of active elements in it. The above objective is normally achieved in two steps.
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.
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.
