Where does the word extension lead come from?

The term "extension lead" originated from the use of electrical extension cords, also known as extension leads, to provide additional power outlets in areas where they are not readily available. The word "extension" in this context refers to the fact that these cords extend the capacity of the electrical wiring in a building, allowing devices to be plugged in further away from the wall socket. The literal meaning of "lead" comes from the fact that these cords consist of electrical wiring with a plug on one end and sockets on the other to allow for multiple devices to be connected. The term "extension lead" has now become a commonly used phrase in the English language to describe these useful items that enable us to power our gadgets and appliances from a distance.
