Electrical sockets serve as points of connection between electrical devices and the power supply. They typically consist of an outlet and a set of terminals for plug insertion. Key aspects include:

1. *Power Distribution:* Sockets facilitate the distribution of electrical power from the grid to devices, enabling them to operate.

2. *Plug Compatibility:* Different socket types accommodate various plug configurations, ensuring compatibility with devices and appliances.

3. *Safety Features:* Sockets may include features like grounding for safety, and some are designed to prevent accidental contact with live parts.
