Electrical Math Workbook

This workbook is for electrical apprentices, trade-school students, helpers and electricians who want to get faster and more confident with the math of the trade: Ohm's law and power, series and parallel circuits, wire resistance and voltage drop, three-phase power, motors and transformers, conduit bending, and estimating a job. It is math practice, not wiring instruction. It does not replace your training, your instructor, the manufacturer's instructions or the electrical code adopted in your area.

• A short lesson and worked examples at the start of every unit
• Practice problems drawn from real jobsite situations
• A full answer key, with every answer calculated and checked by computer

For practice and study. Always follow your plans, manufacturer instructions, local codes and your instructor or supervisor.
