company. - Physics. Also: why is switch connected in live wire? True or False. The neutral wire completes the circuit and carries current away from the appliance.
The neutral wire is also supplied from the power station and is used to complete the circuit. So, it is always better to cut off the supply which is given from the live wire. The third wire, called the earth wire (green/yellow) is a safety wire and connects the metal case of the appliance to the earth. If something goes wrong inside and the live wire gets accidentally connected to some metal part, the circuit breaker will blow, protecting the user from an unpleasant sensation or even electrocution. Live wire: A ‘live’ or ‘hot’ wire is a wire that is connected to a power source. The live wire is connected directly to the generators of the current supply company. generator after it has passed through the appliance. Live/hot wires may be brown, red, black, blue or grey. The live wire coming out from the output terminal of kWh meter has another fuse in it which is called the main fuse. The live wire is connected directly to the generators of the electricity supply company. Photocopying Permitted.
The earth wire is there as a safety
this wire either! In case of any short circuit, the fuse will be the first one to blow out disconnecting the circuit preventing current from reaching any other point saving ones life. the circuit. Detailed answer pplease. Take the second letters of the words blue, brown and striped. The Earth Wire. The neutral wire returns

It is usually connected to the metal casing of the appliance. This means the wire has a high potential voltage, whereas a human has zero potential voltage and so there's a big potential difference between them. The main fuse is connected to the live wire. Directed by Christian Duguay. What is the Live Wire? GCSE Physics. Informal A vivacious, alert, or energetic person. carrying the same electricity as the live
This varying voltage (an AC supply) causes a current to be pushed through the live wire. In a plug, the blue neutral wire goes to the left, the brown live wire to the right and the green and yellow striped earth wire to the top. The diagram shows the key features of a three-pin mains plug: There is an easy way to remember where to connect each wire.

wire. Live wires are dangerous because they carry current to the appliance they're connected to, at very high voltages. The neutral wire completes the circuit. If there is a fault-e.g. When the appliance is working correctly, the live wire supplies the electricity which flows through all of the components. The fuse wire is always connected in the live wire of the circuit because if the fuse is put in the neutral wire, then due to excessive flow of current when the fuse burns, current stops flowing in the circuit, but the appliance remains connected to the high potential point of the supply through the live wire.
