One important thing about electricity is the plugs and wires, and when you need to repair them, you might notice that the different coloured wires are inside a plug.
The power that comes from the national grid is the main power supply, the current of the mains is an alternating current with around 240 volts flowing into households, keep in mind that the voltage may differ between, which goes into our sockets in our homes.
Three wires are in a plug, the live one, the grounded or earth wire and the neutral one, with all of them having an insulating plastic covering the copper wires.
Now the way we differentiate the wires so that we don't shock ourselves is the colours, brown being live meaning all the voltage flowing through the plug is going through the brown one and has the potential difference of 230 volts, the blue one is the neutral one that will complete the circuit, and lastly is the earth or ground wire, which is a stripped green wire and means
