Learning physics on my own as an electrician/technician. What topics should I learn?

I am currently doing physics, advanced functions, and calculus on a high school level in Khan Academy.

Besides physics covered in high school do i need to study anything else to as a prerequisite to learn and understand the more interesting topics like induction, magnetism, a more advanced electrical theory, power generation and how to turn motion into energy.

I am planning on going into electrical engineering technology and I am naturally curious in learning about electric motors, transformers, electrical theory and power generation. I want to really take a couple years to learn these topics at my own pace. But I don't think I could deep dive into any of them since I never took any grade 12 math classes and it's been over 12 years.
