Electrical & Wiring
Power, the control system, and legal wiring.
The Electrical & Wiring branch covers the complete FRC control system power chain: the 12V SLA battery, the 120A main breaker, the power distribution device (REV PDH, CTRE PDP/PDP 2.0, or AndyMark PD), the roboRIO controller, the Vivid-Hosting VH-109 radio, motor controllers, and the wires and connectors that tie it all together. You will learn how to read the legal wiring rules from the FRC Game Manual, pick the right wire gauge for a given current, and crimp connections that survive a full competition season. Mastering this branch is the difference between a robot that drives flawlessly and one that browns out on the field.

The learning path
Modules & lessons
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.
