Two reasons:
1. Alternating current does not loose as much power over long distance.
2. Alternating current can be stepped up or down through Transformers, allowing AC to be transmitted at high voltage (even less current loss) and then it can be stepped back down inside your home.
For short distances and if there is no need to step up or down, DC is fine.

What are the principle of electricity?
direct current alternating current
What piece of equipment is used to produce electricity?
Some possible answers are: a battery (which produces direct current) or a generator of electricity generator, such as a dynamo (which produces direct current) or an alternator (which produces alternating current).
The kind of electricity from the power plant is called?
There are only two kinds of electricity, direct current and alternating current. All power plants now produce alternating current
Is electricity AC Or DC currant which one?
Electricity or rather electric currant can be either AC or DC. AC means alternating current (as in that electricity that is supplied by the mains) and DC means direct current (as in that electricity supplied by a battery)..
What are the two kinds electricity?
Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction. In AC (alternating current), the current regularly changes its direction.Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction.

What are the two basic types of electricity?
The two basic types of electricity are static electricity and current electricity. Static electricity involves the build-up of charge on an object, while current electricity is the flow of electric charge through a conductor.
What form of electricity comes out of a Wave Generator?
It depends on how the generator is set up. Some will produce DC (Direct Current) and others will produce AC (Alternating Current). Where possible AC electricity will be produced as it runs through the grid without much loss of power.
What are the five types of electricity?
Static electricity Current electricity Direct current (DC) Alternating current (AC) Electric power
Does a flashlight use a direct current of electricity?
Yes, a flashlight typically uses a direct current (DC) of electricity. The battery in a flashlight provides this direct current to power the light bulb or LED.
Lightning carries Alternating current or Direct Current?
Power lines carry electricity as alternating current.
What is one way of producing electricity?
One way of producing electricity is through the use of solar panels. Solar panels convert sunlight into electricity through the photovoltaic effect, which generates a direct current (DC) that can be converted into alternating current (AC) for use in homes and businesses.
What is D-C electricity?
DC electricity is direct current, compared to AC which is alternating current where the current is consistantly changing direction, direct current does not change direction. The main source of DC is a battery.
What supplies direct current?
device what produce dc are battrey genorators
What types of electricity are used in an automobile?
Direct current.
When you talk about electricity what does DC stand for?
Direct Current
Is the electricity from batteries AC or DC?
Direct current
What type of electricity is found in batteries?
direct current
