How does a plug differ from a socket?

A plug is designed to connect into a socket to establish a secure electrical connection. When you insert a plug into a socket, it completes the circuit, allowing electrical current to flow from the socket, which is usually connected to an electrical supply, through the plug and into the appliance or device that the plug is attached to.

This connection is essential for the operation of electrical devices, as the socket provides the energy, while the plug serves as the interface that allows devices to draw that energy. The design ensures that devices can be easily connected or disconnected from a power source, promoting safety and convenience.

Understanding the roles of plugs and sockets is crucial in electrical safety and functionality, as it helps in properly wiring and using electrical equipment.
