Course description
In Alternating Current Fundamentals , you'll learn ...
- The advantages and disadvantages of alternating current (AC) relative to direct current (DC)
- The relationships between magnetism and electricity
- How to calculate values of voltage and current, as well as phase difference between sine waves
- Ohm's Law in AC circuits
Overview
Credit: 2 PDH
Length: 29 pages
This course provides a basic introduction to alternating current (AC) theory. An alternating current is an electrical current whose magnitude and direction vary cyclically, as opposed to direct current (DC), whose direction remains constant. Due to its inherent advantages and versatility, alternating current has replaced direct current in all but a few commercial power distribution systems.
This course is suitable for non-electrical engineers with a desire to understand the fundamentals of alternating current, as well as electrical engineers looking for a refresher course.
