Power, grounding and decoupling
22 min · IntermediateUnderstand the concept
Current returns through conductors and planes. Decoupling helps reduce supply disturbances near active components. Layout should be evaluated for noise, heat and fault currents.

Your exercise
Document power entry, protection, return paths and component limits for a low-voltage board.
Practice in simulation or at safe low voltage unless supervised by qualified personnel. Follow official equipment safety guidance.
