if you have something that rotates 360 degrees, it ends up back where it started. the geometry produces a sine wave. DC generators have a design that switches during rotation, or otherwise they generate AC then convert it.

ac means the polarity shifts due to a coil being turned around a magnet.
because of the motion the electrons 'alternate' direction making it alternating current.

What generates more noise ac motor or dc motor?
dc motors generate more noise.
What can change an ac current to a DC current?
rectifierac motor - dc generator set
Is galvanometer generator alternating current or direct current needed to operate an electric motor?
That depends if it is an ac or dc motor.
What type of current is used in an electirc motor?
Well that depends on the type of motor. DC motors use direct current DC and induction motors use alternation current AC.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
What generates more noise ac motor or dc motor?
dc motors generate more noise.
Alternator generates DC or AC?
An alternator produces AC current but it is converted to DC by the rectifier inside the alternator.
What is AC motor and DC motor?
AC stands for alternating current, and DC is direct current. A motor is a device that uses electrical energy to spin. An AC motor uses AC voltage, and a DC motor uses DC voltage. http://ezinearticles.com/?The-Difference-Between-AC-and-DC-Electric-Motors&id=193767
Can a dc motor works in ac current?
no
What can change an ac current to a DC current?
rectifierac motor - dc generator set
Why a DC motor is called DC motor?
DC, in DC motor, is an acronym for Direct Current, which means that it works on direct electrical supply by a battery. In an AC motor, the motor runs on Alternating Current Supply from other sources other than batteries, such as electricity from your house.No, d.c. is not an acronym. It is simply an abbreviation."a word formed from the initial letters or syllables taken from a group of words"http://www.thefreedictionary.com/acronymYes, a word. "dc" is not a word.
How do you change the connection of single line to 3 phase line of DC motor?
There is no such thing as 3 phase to a DC motor. DC is direct current and is totally different from AC. 3 phase only exists in AC or Alternating Current
Which type of current does a dc motor use?
dc stands for direct current. This can be obtained from a battery or a rectified ac (alternating current ) supply.
Is galvanometer generator alternating current or direct current needed to operate an electric motor?
That depends if it is an ac or dc motor.
What is an alternator for?
The alternator generates power to run the car and charge the battery. An alternator in a vehicle generates Alternate Current (AC) instead of Direct Current (DC) electricity to power the vehicle.
What type of current is used in an electirc motor?
Well that depends on the type of motor. DC motors use direct current DC and induction motors use alternation current AC.
Will an AC electric motor run on DC?
No ... AC means Alternating Current - DC means Direct Current. DC is used mostly for electronics and for voltages within our vehicles. AC is used for motors and for our household appliances and lamps.
