120V to most outlets and switches. 240V to most appliances. If you have a three phase panel you could have as much as 480V or more coming into the panel, but that is usually for commercial applications.
There are two wires running out of the transformer at the power pole and three wires running to the house.
The two from the transformer are insulated, and the third one is bare. The bare wire is the ground wire. The two insulated wires each carry 120 volts, but they are 180 degrees out of phase so the difference between them is 240 volts. This arrangement allows a homeowner to use both 120-volt and 240-volt appliances. The transformer is wired in this sort of configuration:

The house is fed with 240v, coming in two 120v lines.
