For Beginners/Hobbyists:
* Coursera & edX: These platforms offer courses from universities and other institutions worldwide, some focusing on introductory electrical engineering concepts. Look for courses with titles like "Introduction to Electrical Engineering" or "Circuits and Electronics." While some courses are free to audit, certificates often require payment.
* Udemy & Skillshare: These platforms offer a vast library of courses, including many on basic electronics, Arduino programming, and home electrical repair. They're generally more affordable than university-level courses but might lack the academic rigor.
* YouTube: Numerous channels offer free tutorials on basic electronics, troubleshooting, and specific projects. This is a great resource for visual learners but requires careful selection of reliable channels. Look for channels with strong reputations and numerous positive reviews.
For Intermediate/Advanced Learners:
* Coursera & edX: As mentioned above, these platforms also offer more advanced courses in specific areas of electrical engineering, such as power systems, control systems, and signal processing.
* FutureLearn: Similar to Coursera and edX, FutureLearn offers university-level courses, some focusing on more specialized aspects of electrical engineering.
* Online Universities: Many universities offer fully online electrical engineering degrees or individual courses. Examples include Oregon State University, Georgia Tech, and the University of Illinois. These will be the most rigorous and academically focused options.
* Specific Industry Training: Some companies offer specialized training in areas like industrial automation, PLC programming, or electrical design software. These courses are often tailored to specific industry needs.
Things to Consider When Choosing a Course:
* Your skill level: Choose a course appropriate for your current knowledge.
* Course objectives: Make sure the course covers the topics you want to learn.
* Instructor credentials: Look for instructors with relevant experience and expertise.
* Course reviews: Read reviews from previous students to gauge the quality of the course.
* Cost and certification: Consider the cost of the course and whether you need or want a certificate of completion.
* Time commitment: Assess how much time you can realistically dedicate to the course.
Remember safety is paramount when working with electricity. Many online courses emphasize safety precautions, but always prioritize your safety and consult professional electricians when dealing with mains voltage or potentially dangerous situations.
