In the United States and most western countries, the "line frequency" is 60 Hz. (formerly referred to as 60 "cycles per second"). In European and many Asian countries, the frequency is 50 Hz.
Due to the difference in line frequencies, devices with INDUCTORS (AC motors, Transformers, etc.) are NOT interchangeable between 60 and 50 Hz. power sources.
The standard line VOLTAGE in the United States started out (circa 1940s) as 110 volts. Over the years, the "standard" was increased in steps of: 110, 115, and currently (no pun intended) 120 VAC.
Again, many European and Asian countries have utility power voltages in the 220 VAC range.

Answer
Supply frequency depends on where you live. In North America and parts of Japan, for example, the frequency is 60 Hz. On the other hand, in Europe and in much of the other parts of the world, the frequency is 50 Hz.

Electrically how is AC different from DC current?
DC is direct current, current travels in one direction. AC is alternating current, current changes direction twice per cycle. 60 Hertz would change direction 120 times per second.
How do you convert hertz into volts?
'Hertz' is the modern name for 'cycles per second' and represents how many times an alternating current (AC) changes from + to - per second and has nothing to do with voltage that can be either AC or DC. Tus if you have an alternator and can rotate the shaft 60 times per second with a voltage of 120 volts you will produce the same AC voltage that you find in your wall outlet (Alternators produce AC while generators produce DC electricity.
What measurement can vary with AC current by not DC current?
HZ. Hertz is the name given to the frequency of the alternating circuit. Direct current (DC) has no frequency since one wire is always positive and the other is always negative; but AC (Alternating Current) rapidly changes polarity, and does so at a rate that is defined by HZ.
How many hertz in direct current?
Direct current has no frequency, it has voltage. also it has current that is measured in Amperes which is dependable of the resistance of the circuit. Alternating current has frequency because the electricity flows alternatively on both directions. If the frequency of AC is 50hz/s it means that the electricity flows forwards and backwards 50 times per second.
What is alternating current and give examples for this?
Alternating Current( AC ) constantly reverses itself as a result OS reversing electromotive force.One complete reversal is a cycle,and the number of cycles per second is the frequency of alternating current .The standard frequency of alternating current in the United States and the rest of North America is 60 Hz(1 Hz or hertz,equals 1 cycle per second )ex...Transformer,AC generator
What is AC current?
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
How do you calculate starting current of 380 volts 3phase 50 hertz AC motor?
Dear Sir,I want to know that how much draw starting current of 380 volts 3 phase 50 hertz AC motors as per rating values?
Which type of current is used in batteries and which is used in household outlets?
Batteries provide Direct Current (DC) while household outlets provide Alternating Current (AC).
What type of current is flowing in electrical lines?
It's electrical current. Measured in amps.
What does AC mean on ultrasound?
Alternating Current. in the US -ll0-l20 Volts, 60 Cycles or Hertz.
How many hertz are there in a 110 volt in a home?
Household utility AC power is supplied at 60 HZ in the US and most of the rest of North America, and at 50 Hz in most of the rest of the world.
Electrically how is AC different from DC current?
DC is direct current, current travels in one direction. AC is alternating current, current changes direction twice per cycle. 60 Hertz would change direction 120 times per second.
What is ac and what is DC?
DC stands for "direct current", AC for "alternating current". A direct current flows in a single direction; an alternating current changes its direction all the time, typicall 100 or 120 times a second (twice the frequency, which is measured in hertz).
Is my home 240 v ac?
The household supply in the UK is 240 V and is AC (alternate current).
How do you convert hertz into volts?
'Hertz' is the modern name for 'cycles per second' and represents how many times an alternating current (AC) changes from + to - per second and has nothing to do with voltage that can be either AC or DC. Tus if you have an alternator and can rotate the shaft 60 times per second with a voltage of 120 volts you will produce the same AC voltage that you find in your wall outlet (Alternators produce AC while generators produce DC electricity.
What kind of electricity does America use?
America uses 60 Hertz (Hz) Alternating Current (AC). Most smaller devices operate on 120 volt current.
What is my 240 v supply at home ac or dc?
The household supply in the UK is 240 V and is AC (alternate current).
