What is the frequency of a 440 volt electrical supply?
The frequency of any alternating current (ac) electrical supply always depends on the frequency at which the supply has been generated.That is true no matter whether it was generated at a power station, for use in a home or factory, or in a dc-to-ac power inverter unit, for use in, say, a vehicle or boat.Power stations in USA, Canada and other countries generate ac at 60 Hz.Power stations in countries in Europe and other world areas generate ac at 50 Hz."Hz" is short for "hertz" which is the name used internationally for "one cycle per second".
What is the frequency of the ac sine wave?

Why do transformers work only work on an AC supply?
Transformers only work on ac supply because it principle is mutual induction. DC supply has constant magnitude whereas AC has alternating magnitude. so we can step up or step down current/voltage in transformer in ac only.
Does a ac generator have a brush?
AC generators (alternators) usually have a dc supply to the rotor coils, supplied through slip-rings with carbon brushes. Because the slip-rings can be made very smooth the life of the brushes is greatly extended when compared with brushes on the commutator of a dc motor or an ac commutator motor. Cars generate electrical power with a three-phase AC alternator, connected directly to the battery through rectifier diodes. The alternator voltage is controlled by the voltage regulator, which works by controlling the dc supply to the rotor.
Is schrage motor ac?
As the motor is a three phase machine,it must be AC supply
Can an ac motor generate electricity?
An ac motor cannot generate electricity but its shaft can be coupled to that of certain devices like an alternator to in order to generate electricity.

Can an amplifier can be operated on ac supply?
Yes, an amplifier can be operated on ac supply.
Why ac current attract?
As we touch an ac supply in which due to body resistance , we create a phase difference between the ac supply and us . As ac reverses polarity , so do we , but our polarity change is opposite to that of the polarity change of ac supply , hence our body gets attracted to the ac supply .
How can you build a dynamo for producing electricity?
A dynamo uses the same physics as an electromotor. Get yourself any electromotor. Spinning it will generate some AC voltage at the power supply contacts.
What is the bahaviorS of the INDUCTOR in ac supply?
Because of Ac supply, current lags voltage by 90 in Inductor.
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
What is the ac power supply in Thailand?
Is it 220 ac or 240 ac in Thailand
How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
What is the meaning of 230V ac and 50Hz ac supply?
It is an AC supply with an rms voltage of 230 v and a frequency of 50 Hz, as used throughout Europe.
What is the use of regulator?
ac supply converted with dc supply
What is the use of a regulator?
ac supply converted with dc supply
