Electricity in the house
Content
Electricity is now such an integral part of everyday life that we often do not attach much importance to it. However, you wouldn't be reading this without electricity! Here is some information about basic electrical engineering concepts that apply to most households.
Wires in a plug
The three pins/pins on a standard UK plug have different purposes. If you were to remove the back of the plug, the blue neutral wire would be on the left. The earth/earth wire will be green and yellow and located on the top contact, and the brown live wire will be on the right and attached to the contact via a fuse. On the body of the plug, the terminals are often marked. with E, L and N (earth, live and neutral) or with the colors of the corresponding wires.Although electrons move back and forth in AC circuits, there is only one hot wire because the blue wire is grounded (neutralized) upon entering the property before it reaches any outlets.
The ports in the socket correspond to the wires in the plug. The three-prong UK plug with earth and fuse is officially known as BS 1363.Electricity levels in the network
In the UK, there is a standardization of electricity levels, which means household voltage is around 230V and has a frequency of 50Hz.What is household electricity used for?
In a typical British household, most electricity is consumed for entertainment purposes - TVs, computers, sound systems, game consoles, etc. The next three main uses are heating, lighting and cooling.
