NCCER Electrical Theory (26104) Alternating current behavior, circuit analysis using Ohm’s Law, and transformer fundamentals dominate this assessment. You’ll need clarity on how voltage, current, and resistance interact across different circuit configurations, plus the physics behind inductance and capacitance in real systems. Power calculations and reactive components separate confident technicians from those guessing through troubleshooting scenarios.
