The ability to repair basic house wiring in you home is a skill you can acquire. Knowing how circuits work and what can be done with them is useful knowledge. Wiring in a residential house is not that complicated, but it can be dangerous. Proper understanding and cautions are required.
Most homes in the United States have two hot wires and one neutral coming into them. Supplying a stated 240/120 volts. The actual voltage received is normally slightly less 230/115 volts. This type of power is commonly called single phased power. Most residential homes have this type of basic house wiring.
The power coming into your home is also called alternating current. There are people in the world that can explain what that means exactly, but none of them are writing this article. Alternating current is used to allow electricity to be transported over long distances. Leave it at that, the guys that can explain it will talk in a language you won't understand.
The first power plant using alternating current came on line in Niagara Falls, New York in 1894. Nikola Tesla is credited with the development of a system the would allow power to sent long distances. Thus, making it practical.
When you use one hot wire and the neutral you get 115 volt power. Most small electrical devices and lights run on this current. Heavy duty items like ranges, hot water tanks and dryers use both hot wires and the neutral to achieve 230 volts.
You may not want to tear into replacing you electrical service, but doing some basic house wiring may not be out of the question. The first thing you want to do is get a healthy respect for electricity. It is dangerous and can hurt or kill you. Take precautions when working around electricity.

WARNING!! Make Sure the Power is OFF Before Working With Electricity!!! WARNING!!!
In addition you need to take it one step further. Have a non contact voltage tester with you and check the box before you mess with it. It is possible for more than one circuit to run through the same box. You may have shut one of them off, but there could still be hot wires in the box. The number of combinations you can find in basic house wiring is staggering. Always double check.
Circuits in panel boxes are sometimes poorly marked. It may take some experimenting to get the right circuit. Take the time and make sure the power is off. Take a look at the article 'Electrical Safety Tips' for a more information on electrical safety.
