What you will learn

This course will provide an understanding of alternating sinusoidal current.

including sinusoidal waveforms,

including vectors & phasors,

including reactance & impedance.

Why take this course?

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

Our review

📚 **Course Review for AC Circuit Analysis** Overall, the course has received a high rating of 4.70 from recent reviews. The feedback from learners has been predominantly positive, highlighting the effectiveness of the course's content and presentation style. ### Pros: - **Comprehensive Content**: Reviewers praised the course for its thorough coverage of AC Circuit Analysis, with one learner noting that it provides the fundamentals necessary to understand the subject. - **Clear Explanations**: The explanations provided in the course were described as clear and free from unnecessary complications. This clarity was particularly appreciated by learners who may have struggled with complex topics. - **Effective Diagrams and Automations**: Several learners pointed out that the diagrams and automations in the course were instrumental in helping them grasp difficult concepts, making the material more accessible. - **Diverse Topics Covered**: The course was commended for its comprehensive approach to AC circuits, with a focus on power calculations, inductors, capacitors, and their behavior within AC circuits. - **Paced for Understanding**: Despite some learners' brains being "hyperactive," the pace of the course was generally considered appropriate, allowing for better comprehension and understanding of the underlying concepts behind each formula. - **Helpful Tips for Memorization**: The course included practical tips to help students remember difficult parts, which one learner credited with improving their grade in Electricity 1. - **Excellent Teaching Quality**: One reviewer, who holds an electrical engineering degree and is preparing for a job interview, found the teaching quality to be superior to that of their university professors and recommended that the course creator market his course to USA universities, not just for students but also for educators. ### Cons: - **Use of Complex Numbers**: One learner noted that the math in the course was challenging because it focused on complex numbers, which differed from their college's approach using the Pythagorean theorem. However, they acknowledged that this might not be the course's fault and could be a matter of personal adaptation or learning style. - **Language Barrier**: One non-native speaker learner mentioned potential difficulties understanding the course material due to language barriers, but also pointed out that with more focused study time, they would likely understand everything better. In summary, this course on AC Circuit Analysis has been highly regarded by learners for its clear and comprehensive content, effective teaching methods, and helpful diagrams and automations. While there were some mentions of challenges related to the use of complex numbers and language barriers, these were isolated comments and did not detract from the overall positive feedback. The course is recommended for anyone looking to understand AC circuits better, whether for academic study or professional development.
