Be sure to review the EMDC Handbook for specific rules related to electrical components. 

An electrical component in a chain reaction machine refers to a module or device that is powered by the flow of electrical charges to trigger or contribute to the overall chain reaction process. Charges can flow through switches, circuits, pulleys, sensors, or other devices to control the electricity to create movement, activate mechanisms, or control different parts of the machine. 

It is essential to prioritize safety when incorporating electrical components into a chain reaction machine design. Participants should have a solid understanding of electrical principles, wiring techniques, and safety precautions. They should also be aware of potential hazards associated with electricity, such as electric shocks, short circuits, or overheating. Providing detailed guidelines, safety instructions, and supervision throughout the design and construction process will help ensure safety.
