Create reference sheet based on these test objectives: Physics Unit 6 Study Guide: Electricity & Circuits 1. Coulomb’s Law (Electric Force) • Formula: F = k (q1 × q2) / r² • k = 8.99 × 10■ N·m²/C² • Always convert: µC to C (×10■■) and cm to meters (÷100) • If distance doubles, force becomes 1/4 as strong. • If one charge doubles, force doubles. 2. Electric Fields & Devices • More field lines = stronger electric field. • Field lines spread out = weaker field. • Like charges repel (lines bend away...

This review provides a comprehensive overview of key concepts in electricity and circuits, including Coulomb's Law, electric fields, charge distribution, series and parallel circuits, Ohm's Law, and electrical power. Students will learn to calculate electric forces, understand electric field line properties, differentiate between motors and generators, and master circuit resistance calculations. Practical applications, essential formulas, and tips for avoiding common errors are included to enhance understanding and preparedness for assessments. The resource also includes practice problems that progressively increase in complexity, allowing for effective review and mastery of the material.
