Electrical basics & advanced concepts

This category is where we break down electrical theory in plain language, from true beginner level to more advanced concepts.
Voltage, current, resistance, power, power factor, inductors, transformers, motors, generators, semiconductors—if it’s core electrical theory, Electrical basics & advanced concepts lives here.

Examples are based on everyday U.S. situations (120/240-V residential power, common appliances, basic HVAC, small motors), so you’re not just memorizing formulas—you’re connecting them to what you actually see at home or on the job.
