Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.
The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. These types of alternating current carry information such as sound (audio) or images (video) sometimes carried by modulation of an AC carrier signal. These currents typically alternate at higher frequencies than those used in power transmission.
This course deals specifically with sinusoidal waveforms and will provide the student with the basic understanding of working with circuits involving Alternating Current, which includes sinusoidal waveforms, vectors & phasors, reactance & impedance of R,L,C circuits, as they relate to the basic laws and theorems of electricity. This includes working with AC Power, Power Factor, Resonance, Complex Numbers, Reactance and Impedance
This course is intended for Engineers, Technologist, Technicians, Students wishing to learn and understand or just review the Basic Fundamentals of AC Circuit Analysis.

The rules vary between states, but state boards typically accept a continuing education activity that meets the following criteria: “A course or activity whose purpose and objective are clear with a content that will maintain, improve or expand the skills and knowledge of the licensee’s field of practice.”
Online courses are accepted by all states that require engineering continuing education provided that the student passes a quiz to successfully complete the course, the quiz is graded, and the results are kept on file by the platform provider for a prescribed length of time (the number of years varies for each state).
Automatic certificate of completion will be generated after completing the course.
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz.
