The 0V line in the middle is the voltage of your neutral line. AC power oscillates at 60 cycles per second 60 Hz in the U. Other parts of the world use a 50Hz standard. With the two legs feeding your house being out of phase, can you pick up V AC by using both legs rather than one leg and neutral.
The neutral wire is not utilized in a V circuit as the current is fed by one leg and returned on the other leg. Electric power comes in two basic flavors: AC and DC. DC power flows continuously in one direction, ideally never switching or fluctuating.
AC current switches from positive to negative and negative to positive many times a second. Voltage is a measure of "circuit pressure. The voltage helps to determine the amperage—the amount of electricity flowing through the circuit every second.
The higher the voltage, the harder the electricity pushes on a circuit and the more electricity flows through it. AC is also measured in frequency—how fast it changes direction. Most AC power is at 60 hertz, which means that it changes from negative to positive to negative again 60 times a second.
Most of the United States uses electricity at anywhere from to volts AC. The electronics we build are designed so that they can handle this slight power variation without malfunctioning. Latest posts. Question Ram speed,size whats better to chose? Latest: Endre A moment ago.

England and Wales company registration number Question No more power. Yesterday at AM. Question Case and power supply compatibility.
Sunday at AM. But appliances are usually designed to work with a range of voltages. What does a plug look like? If volt appliance is under 15 amps a regular 3-prong cord is used. Why does the United States use v? Once AC was widely accepted as being superior to DC for power distribution, V became the standard for AC distribution presumably because it used the "safer" Voltage level of the DC system.
After metal filament lamps became feasible, V became common in Europe because of the lower distribution costs. Can you plug an air conditioner into a regular outlet? If the AC does not have a standard grounded plug, it must require more than 13 amps. If it requires no more than 15 amps, it could be connected to the proposed circuit, but code requires that there be no other outlets on the circuit. If it requires more than 15 amps, it requires a higher capacity circuit. Is v better than v?
For the same load power demand , using V requires less current than using V. That's exactly the reason why power lines used to transport power are using high voltage tens of thousands of volts. So yes, V is more efficient than V.
