Are you struggling to understand the math behind electricity? You're not alone—many aspiring electricians and technicians find electrical theory overwhelming. This course is designed to change that. It takes the mystery out of formulas, triangles, and waveforms by breaking down the math of electricity into plain, understandable steps. No jargon, no confusion—just clear learning that builds your confidence.
You'll start with the basics of trigonometry and move gradually into core industry skills like impedance triangles, vector math, and AC waveform generation. Whether you’re new to the trade or already on your way to becoming a journeyperson, you’ll learn how to calculate right-angle triangles, analyze circuit vectors, and understand the behavior of alternating current in real electrical systems.
By the end of the course, you’ll be equipped to interpret and compute electric values using impedance and power triangles, apply vector addition to circuit analysis, and explain voltage generation in alternators. These skills are essential for troubleshooting, maintaining phase alignment, and safely handling inductive loads. Master the math that powers the modern world—and take the next step in your electrical career. Enroll today!
