Wiring refers to the system of electrical conductors that connect various devices and components in a building or electronic device. It allows electricity to flow from a power source to appliances, lights, and outlets, enabling them to function. Proper wiring is essential for safety and efficiency, as it prevents electrical hazards and ensures that devices receive the correct voltage. In homes, wiring is typically hidden behind walls and ceilings, but it plays a crucial role in everyday life. Different types of wires, such as copper and fiber optic, are used for various applications, from powering kitchen appliances to providing internet connectivity.
