Wiring and circuits are essential components of electrical systems. Wiring refers to the insulated conductors that carry electrical current, while circuits are closed loops that allow electricity to flow. Together, they enable the operation of various devices, from simple light bulbs to complex machinery. In a circuit, components like resistors, capacitors, and switches work together to control the flow of electricity. When a circuit is complete, electricity can travel through the wiring, powering devices and allowing them to function. Understanding wiring and circuits is crucial for anyone working with electrical systems or devices.
