The Complete Electrical Theory Bible

You can pass the class and still not know what the meter is telling you.

Apprentice theory is taught either as pure mathematics with no connection to the van, or as site rules of thumb with no explanation of why. Neither leaves you able to read a circuit.

Seven self-contained books in one volume: 174 pages, 8.5 x 11 inches, 70 chapters. Each idea is taught, then immediately connected to what it looks like on a real circuit and what a wrong reading would mean. Every practice problem is original and every right-hand page is working space.

What's inside

• Book 1 - The quantities - voltage, current, resistance and power, defined properly
• Book 2 - DC circuits - series, parallel and the free sanity checks on each
• Book 3 - Magnetism - the one pair of facts behind every motor and transformer
• Book 4 - AC fundamentals - where DC intuition stops working, and phase has to be understood
• Book 5 - Reactance and power factor - what separates wiring from diagnosing
• Book 6 - Motors and three phase - slip and back-EMF made obvious rather than memorised
• Book 7 - Test instruments - reading a fault from the meter, and proving before and after

Predict before you measure. Writing down what you expect turns a reading into a test.

For apprentices, trainees and anyone taught the rules but never the reasons.
