It depends on where you live in the world. In North America there are two types of services, single phase and three phase. Single phase is usually used in homes and three phase is used for commercial and industrial installations. Single phase home services are 120/240 volts and can be identified by there being three wires coming to your home and into the service head drop. Three phase services are now usually a wye connection and are identified by there being four wires that go into the service head. These voltages could be 120/208, 277/480 and 347/600.
Service Electric was created in 1948.
Nashville Electric Service was created in 1939.

To determine the direction of the electric field, you can use a positive test charge. The direction of the electric field is the direction in which a positive test charge would move if placed in that field.
Southwestern Electric Service Company merged into TXU Corp in 1993.
From an electric field vector at one point, you can determine the direction of the electrostatic force on a test charge of known sign at that point. You can also determine the magnitude of the electrostatic force exerted per unit charge on a test charge at that point.
To determine the charge density from an electric field, you can use the formula: charge density electric field strength / (2 epsilon), where epsilon is the permittivity of the material. This formula relates the electric field strength to the charge density of the material.
Through the service drop to your house.
If you're using it in reference to electrical service it generally means non-business hours. Off-peak electric service for instance is electric service that is at a much lower rate, however the electric company shuts off the service for a certain period of time each day, usually during the highest demand.
To determine the electric flux through a surface, you can use Gauss's Law. This law states that the electric flux through a closed surface is equal to the charge enclosed by the surface divided by the permittivity of free space. The formula for electric flux is E A cos(), where E is the electric field, A is the area of the surface, and is the angle between the electric field and the normal to the surface.
