Both hot wires and the neutral wire make a volt circuit for large appliances such as air conditioners and electric furnaces. An electric meter, monitored by your electric utility company, is mounted where the electricity enters your house. The main panel is usually right next to or under the meter. This is the central distribution point for the electrical circuits that run to lights, receptacles, and appliances throughout the house.
A circuit, by definition, is a circular journey that begins and ends at the same place, and this is essentially how electricity works. Current begins at a power source, powers the appliance or device along the circuit, and then returns to the power source. Any interruption in this path will render the circuit dead. A circuit consists of a hot usually black wire that goes from the main panel to a series of lights, receptacles, or appliances, and a neutral usually white wire that returns to the main panel.

The power in factories is three-phase power, made out of three different AC electric signals which are out of sync with each other. Every time you change energy from one form to another, you lose some energy.
Generators make electricity as AC, so it makes sense to transmit it in that form. The electricity generated is extremely high in voltage, which minimizes the amount lost over the power lines. Individual buildings, however, use much lower voltage. The electricity is run through a step-down transformer, a device that lowers the voltage of AC electricity. If the electricity in the power lines were DC, it would have to be converted back to AC at every transformer before it could be stepped down—a wasteful process requiring a lot of extra equipment.
Most electronic devices can not actually run off of AC current. Instead, they need steady, low-voltage DC power. That is why nearly every consumer device that plugs in has a DC power supply. The power is first run through a second step-down transformer to lower it from volts to some value usually between 5 and Then it is run through a bridge rectifier, which turns the power into DC. If you travel internationally, the differences between AC power standards in different countries pose problems for mobile electronic devices.
