Alternating Current can be transmitted efficiently at high voltagesbut low currents, for a given power, since at its simplest, Power in Watts = Current X Volts. This minimises heating losses (proportional to resistance-squared) in the cables.
Alternating-current Voltage is also easily stepped up or down by a transformer, not possible with D.C.

Why cant you generate DC directlyinstead of generating AC and converting it to DC?
Yes, by using a dynamo (which produces d.c.) instead of an alternator.
Is bulb operate on ac or DC?
It can be operated using both AC or DC
How you convert DC TO ac?
we can convert a dc supply to an ac supply using inverters. Its a common operation which we observe in our daily lives dc can be converted to Ac using an undulator.
What is reason behind using dc emf in compare to ac emf?
The main reason for using ac is safety. ac as more safe than the dc as it passes through zero in every half cycle. There are many other reasons like, ac can be transmitted for longer distances efficiently we can use the Induction motor.
What are the roles of a diode and a capacitor in an AC-DC converter?
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
What component converts AC into clean DC power?
By using rectification we can convert the AC into DC....
Why not you use ac instead of dc to electronic components?
AC is easier and cheaper to send from the generators to the consumers than DC is.
Are TV's in buses AC or DC input?
Televisions in buses can be either AC or DC current. It depends on whether the bus is using a DC to AC power convertor or an AC generator or DC power from the battery.
Where would DC be used instead of AC?
DC is used for extra-high voltage transmission systems, as there are less losses with DC than with AC, and no synchronising problems.
Can you use AC instead of DC for superposition theorem?
Yes, the theorem still applies for AC.
How do you make ac into DC in a ac transformer?
You can not change AC into DC using a transformer. A transformer changes the voltage levels. To change AC into DC, you would need a rectifier. To change that into smooth DC you need a capaciter and a voltage regulater
Can you build a Joseph Newman motor using AC instead of DC and how?
Probably not. For more information click on the Related Link shown below.
