What are the different voltages?
North American Voltage Ranges 1 110 and 220 Volts#N# 2 The designations "110 volt" and "220 volt" represent an older, out of date standard that's no longer found in new equipment. However, this terminology is still familiar to many people, so it remains in use. 3 #N#115 and 230 Volts#N# 4 The terms "115 volt" and "230 volt" come from product design standards. Electrical devices are usually designed to operate in this range, plus or minus 10 percent. This makes it easier for homeowners to find an outlet that will power their device. 5 #N#120 and 240 Volts#N# 6 The power delivered to your home is 120 or 240 volts. This is called "nominal voltage." That means it's the standard voltage as measured at the transformer outside your home. Nominal voltage can vary up to plus or minus 5 percent from its stated definition. 7 #N#125 and 250 Volts#N# 8 The outlets in your home are rated at the maximum voltage expected on the electrical circuit.

Can you drop an extension cord to 110V?
At the end of a long extension cord you could even drop to 110V. This is why you'll see the different terms used. In fact many appliances or devices will be rated to 110V or 115V which basically tells you they are tested to operate down to a lower voltage.
What happens when you use both legs of a circuit?
When you use both legs to feed a circuit, like a range or water heater, you end up with twice the voltage (a line that oscillates from +240V to -240V). The neutral wire is not utilized in a 240V circuit as the current is fed by one leg and returned on the other leg.
