Electricity & Electronics Fundamentals

$99.00

A thorough introduction to the foundational concepts of DC, AC, and Basic Electronics, with a focus on renewable energy and energy storage technologies. Concepts covered include charge, current, voltage, resistance (and impedance in general), series and parallel circuit concepts, DC and AC, Ohm’s Law and Kirchoff’s Laws, power, energy delivery/consumption, etc. Special applications include the “I-V” curves for PV cells and PV system wiring approaches, and fundamental AC power system concepts, including 3 – phase circuits.  After linear DC and AC circuits are covered, the course concludes with an introduction to transistors and diodes. See further details below.

Description

Have you ever wondered what terms like current, amps, voltage, resistance, impedance, watts, and so forth really mean and how they relate to one another? Have you ever wondered how electrical circuits work, and how to predict the power and energy they deliver? Have you wondered exactly how DC and AC circuits differ, and in what respects they are similar? Or what electronic components such as capacitors, diodes, and transistors do and how they are utilized?

If so, or if you need to know these kinds of things to get started in the renewable energy field, then this is the course for you. Taught by an experienced physics and electricity & electronics teacher with special expertise in renewable energy and a love of teaching newcomers to the subject, this course will reveal the mysterious concepts of electricity and electronics once and for all.  You will gain both an intuitive and quantitative understanding of these concepts, and be able to readily grasp the electrical features of renewable energy and (electrical) energy storage devices as a result.

A sample slide on the electrical and power relationships for PV modules wired in parallel. As the slide demonstrates, there is a deep consistency between the electrical relationships for current and voltage and fundamental physics principle of Conservation of Energy. In fact, if one traces the electrical relationships from their beginning, which this course does, one learns that the electrical relationships are completely founded on the fundamental physics principles like Conversation of Energy and also Mass (and hence Charge) to begin with. So the result is not really surprising, but it’s important nonetheless to understand these relationships, and knowing their true foundation actually makes it all much easier to comprehend and remember.

 

It is recommended, although not required, that you take our “Energy Science Fundamentals Course” prior to taking this course. (The concepts of energy and power are common to the material covered in both).

Course Format: To ensure an effective and interactive learning experience, this course, as well as all courses taught by Renewable Energy Now!, are taught in live-Zoom classes. Online assignments are also provided for participants to complete on their own.  To remain in good standing for the Certificate of Completion, participants must attend fully attend all Zoom sessions and maintain proper “netiquette”, including keeping one’s camera on, although non-identifying, innocuous “Zoom names” may be used. Please make sure in advance that you are able to attend all the sessions of a course and that you have adequate internet service to Zoom (including with video) before registering. Please also see the larger discussion of our Professional Netiquette Rules for more detail.

Dates and Times:  Course times are designed to facilitate those with full-time day jobs. (Please let us know however if this does not match your availability, so that we might accommodate you at a later date). Our next offering of this course will take place on:

  • Dates: October 3-5 (Monday, Tuesday, and Wednesday), 2022.
  • Times: 7-9 pm, EST, with a short break in the middle.

After You Register: You will be directed to a page at which you can download a course registration certificate.  Save this in a safe place, or print it out. You will also be sent a Zoom link about 1 week before the course. Simply join the class via Zoom when the time comes (see Course Format & Rules below). If you lose your confirmation or Zoom link, contact us by email at info@renewableenergynow.org. Finally, you will be guided to the course resources and the assignments for the course before or during the first Zoom class.

Refunds:  Refunds may be obtained for registration cancellations up to 24 hours before the beginning of a course. No refunds will be issued after that point for any reason. Your registration will be fully refunded at any time should REN! need to cancel or prematurely terminate a course for any reason.

Professional Online Etiquette: Participants are expected to maintain an attitude of respectfulness and professionalism throughout course sessions.  Instructors reserve the right to remove a participant for unruly behavior without providing a refund. Such removal may occur promptly and without further explanation after an initial warning is issued and a second violation occurs. All sessions will be recorded for documentation purposes but will not be shared with participants or publicly in any manner, unless subject to court order. Your privacy, security, and right to learn in a safe, supportive environment are paramount to us!
