What will I learn?
The General Electricity Course gives you practical skills to handle 120 V single‑phase systems with confidence. Learn Ohm’s Law, power formulas, AC basics, and real versus apparent power, then apply them to circuit sizing, load calculations, and safe wiring choices. You also practice using meters, reading ratings, planning branches, documenting designs, and presenting clear, professional reports for real‑world projects.
