If we have AC Current coming into our homes, then why we have different coloured wires?
In: Physics
Power coming into houses in America comes in on 3 wires. A neutral, and 2 hot wires. The 2 hot wires are 180° part meaning when one wire is at the peak of it’s 120 volts the other wire is at -120 volts. Tying these two together in a circuit allows you to provide power for high power devices like air conditioners, car chargers, hot water heats and electric stoves. Typically the hots come in on a red and black wire while the neutral comes in white and ground is either green or bare copper.
