Live wire, neutral & ground (earth wire) - Domestic circuits (part 1) | Physics | Khan Academy
The live wire of domestic circuits is usually red and is at high voltage. The neutral wire is black and has voltage close to that of the ground. The potential difference between these two wires in India is about 220 V. The earth or ground wire provides safety against faults and current leaks. Earth pin is longer to ensure earth connection happens first while connecting and last while disconnecting any devices.
