Free Basic Electricity Course
Basic Electricity and Circuit Fundamentals
Learn basic electricity with voltage, current, resistance, circuits, power, tools, and safe troubleshooting. Enroll in this free electricity course to understand common electrical work.
About this course
This free basic electricity course helps you understand what happens inside simple circuits before you try to read diagrams or solve problems. You will study voltage, current, resistance, circuit parts, Ohm's Law, power formulas, series circuits, parallel circuits, combination circuits, energy use, kilowatt-hours, overloads, switches, resistors, capacitors, batteries, and other common components.
You will also compare AC and DC power, learn why homes use AC, see how rectifiers work, read electrical symbols, follow basic schematics, and use a multimeter to measure voltage, current, and resistance more safely. The course closes with electrical hazards, GFCIs, everyday safety choices, and when to call a licensed electrician. By the end, you should be able to explain basic circuit behavior and approach simple troubleshooting with better judgment.
Course outline
