Alternating current is used because it is more efficient to distribute over long distances. With DC, a power station would have to be built about every ten miles. With AC, this is several hundred to a thousand miles.
Houses have AC because it would be impractical to convert the AC to DC. If this was done, then there would be a heat producing convertor that would add in some power loss because of the conversion.
What else can I help you with?
Is your house alternating or direct current?
Alternating current. Direct current is used in batteries.
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
Lightning carries Alternating current or Direct Current?
Power lines carry electricity as alternating current.
What converts direct current to alternating current?
To convert direct current to alternating current you need either an inverter or a motor-generator set.
Will a battery supply direct current or alternating current or ac?
direct current.
What is AC power plug?
an AC power plug is one that utilizes AC (or alternating current) to power a device. Alternating current is different to direct current (or DC) in the way that instead of providing a direct source of power, it alternates between negative and positive. Most devices rely on Alternating current due to circuitry reasons
What is the fusing current?
alternating current and direct current
Was direct current or alternating current first?
direct came first
How does alternating current and direct current affect heating ventilation and airconditioning?
how dose alternating current and direct current affect heating, ventilation, and air conditioning
Which would make more shock the alternating current or direct current?
direct current
What is a constant current?
DC or Direct Current. The current is no alternating.
How does a device convert direct current (DC) to alternating current (AC)?
A device called an inverter is used to convert direct current (DC) to alternating current (AC). The inverter switches the direction of the current flow at a rapid rate, creating an alternating current output from the direct current input.
