Alternating current is much more efficient to transmit than direct current. Using Transformers, it can be stepped up to high voltages for transmission over long distances using relatively small conductors, and then stepped down at the destination to provide high current.
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
AC voltage, making AC current available, may be generated in several ways: * AC generator driven by * Steam turbine * Diesel motor * Petrol motor * Water turbine * Inverter from a DC source
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
formula for ac to dc
Choice of electricity defines ac and dc
It is AC, alternating current. To create DC the generated power needs to go through a full wave rectifier.
The generated voltage in a power station is AC voltage, not DC. So, it is never converted to AC, because it is already AC.

AC is easier and cheaper to send from the generators to the consumers than DC is.
ENERGY CAN BE GENERATED ONLY AS A ALTERNATIG CURRENT.THERE IS NO WAYS OF GENERATING ENERGY AS A DC DIRECTY.IN CASE OF DC GENERATION ,AC IS GENERATED FIRST AND THEN RECTIFIED INTO DC. TO UNDERSTAND THIS CLEARLY YOU NEED TO KNOW THE WORKING OF GENERATORS. THE REASONS FOR GENERATING ENERGY AS AC IS ENERGY CANNOT BE GENERATED AS DC.
AC voltage, making AC current available, may be generated in several ways: * AC generator driven by * Steam turbine * Diesel motor * Petrol motor * Water turbine * Inverter from a DC source
DC is used for extra-high voltage transmission systems, as there are less losses with DC than with AC, and no synchronising problems.
Yes, but the DC current generated needs to be turned into AC first.
Yes, the theorem still applies for AC.
yes. we can use...but normally generated power is Ac. so availability of dc is require a converter..
