What will I learn?
The online AC circuits course (in its free or paid mode) Electrical Circuits in Alternating Current from Galileo University teaches you the basic theory of electrical circuits in alternating current (AC). This type of current is the one used in most practical applications, as it allows for the efficient and safe transmission and transformation of electrical energy.
It is aimed at students, professionals, and enthusiasts who want to expand their knowledge in this area. To follow this course, it is recommended to have a prior background in algebra, physics, and direct current (DC) circuits. The course has a rigorous and didactic approach, combining clear and detailed explanations with examples and activities that will help you consolidate your learning. The course also offers additional resources, such as readings, videos, and links of interest, which you can consult to expand your knowledge and delve deeper into the topics that interest you most.
This course is available on the edX platform, one of the most prestigious in the world for online education, founded by MIT and Harvard University. It can be taken entirely for free or by paying a small fee.
Contents of the online AC circuits course, Electrical Circuits in Alternating Current
In the course, you will be able to access the following contents:
- Signals and waveforms: How electrical signals in AC are generated and characterized, and what parameters are used to describe them, such as amplitude, frequency, phase, and RMS value.
- Complex numbers and phasors: How complex numbers and phasors are used to simplify the analysis of AC circuits, and how arithmetic operations are performed with them.
- Elements and impedance: How passive elements (resistors, capacitors, and inductors) and active elements (voltage and current sources) are modeled in AC, and how their impedance is calculated, which is the opposition they present to the flow of current.
- Laws and analysis methods: How Ohm’s and Kirchhoff’s laws, as well as nodal, mesh, and Thevenin and Norton theorem methods, are applied to solve AC circuits systematically and accurately.
- Power in AC: How electrical power in AC is defined and measured, and what components make it up: real power, reactive power, and apparent power. You will also learn the concept of power factor and how it can be improved through power factor correction.
Free or paid AC circuits course
The course has two modalities: free and paid. The free AC circuits course mode allows you to access all course content, including videos, readings, exercises, and discussion forums.
The paid modality also offers the possibility of obtaining a verified edX certificate, which accredits your participation and completion of the course. This certificate can be of great value for your curriculum vitae, as it demonstrates your interest and competence in the knowledge of alternating current electrical circuits. Furthermore, by paying for the course, you are contributing to Galileo University and edX being able to continue offering quality and accessible courses for everyone. If you want to know more about the cost and benefits of this modality, I invite you to visit the course page on edX, where you will find all the information you need.
In conclusion, the online AC circuits course (in its free or paid mode), Electrical Circuits in Alternating Current, is a course that provides you with a unique opportunity to learn the fundamentals of AC electrical circuits and power in a didactic, interactive, and challenging way. Do not hesitate any longer and register for the course now. You won’t regret it!
