Electrical Foundations: Volts, Amps, and Circuits

Before you crimp a single connector on an FRC robot, you need a mental model of how electricity actually behaves. This prerequisite primer builds that model from the ground up: what voltage, current, and resistance really are; how Ohm's Law and electrical power tie them together; how series and parallel wiring change the math; and the wire-gauge, fuse, and safety rules that keep a 12V robot battery from becoming a hazard. Every concept is connected back to the real FRC control system so the theory sticks.

Electrical Foundations: Volts, Amps, and Circuits is the prerequisite module of the Electrical & Wiring guide — the ground the 7 numbered modules after it assume you already have, and The FRC Control System: Meet the Components follows it. It holds 4 of the guide's lessons.
