I use this presentation with my STEM classes when we are discussing Electrical engineering at the beginning of the unit so they have a basic understanding of electricity before we get started with creating a circuit. There is also a worksheet that I have students complete after we have gone through the presentation that helps to show they understand the concepts. I will add it to my store also. It is called Basic Electricity and Electronics Problem Worksheet. Some of the slides have notes in the bottom section to help with information students may need to completely understand some of the concepts.
