Direct current (DC) electrical power from a battery has no phase reversal of the electron flow in the electrical circuit. Electrons always flow from the negative terminal to the positive terminal of the battery in the wires of the circuit.

In alternating current (AC), there is a periodic reversal of the flow of electrons (e.g. current) through the wires of the circuit. 60 Hertz refers to the frequency of that reversal of flow. 60 Hz is equal to 60 cycles per second. So AC current from your wall socket in the United States is reversing directions 60 times each second. The cycling is caused by design of the generators used in the power plants that produce the electricity. The current (polarity) reverses direction 120 times each second. Twice in each cycle on a 60 Hz system. Once to the positive and then once to the negative in one cycle.

# Why is the electrical frequency for AC power 60 Hz in the US and 50 Hz in Europe and how were the frequencies determined?

  Answer   You need alternating current to operate a transformer. (It does not work with DC). Transformers are required to step up and down the voltage which is requ

# What is the time to complete one cycle of 60 Hz AC?

One cycle takes 1/60th of a second to complete.

# You observe a small plaque on an electrical appliance that read 115 volts ac 60 Hz this means that the appliance?

    That the appliance does not need a electrical transformer and uses the US standards for electricity off the grid.

# What does 50 Hz AC mean?

It means that the current passes through 0 50 times a second.

# What is the advantage of 50 Hz ac to 60 Hz ac system?

There really isn't that much of an advantage. Since many countries work with both frequencies, many appliances, especially computers, have the option to run at 50Hz or 60Hz. Y

# What does 60 hertz ac current mean?

60 Hertz Alternating Current means there is electricity available between at least two connections, or one connection and a plane -- that is continuously changing from a posit

# How do you reduce the 60 HZ to 50 HZ?

If you're trying to use a 60 Hz outlet to run a 50 Hz appliance, that that would take electronics so complex and expensive that it's definitely not worth your time, money, o

# If the frequency of an AC voltage is 60 Hz what is the period?

Period = 1/frequency = 1/60 = 16 and 2/3 milliseconds

# What does 60 Hz mean on your LED TV?

60 Hz is the refresh rate. In other words, you get a new image up to 60 times per second.

# Why 60 hz not 50 hz?

Nikola Tesla decided on 60Hz based on a trade-off between the higher transformer/motor/inductor eddy current losses and powerline transmission capacitive leakage at higher fre

# What does 100-240Vac at 50-60 Hz mean?

It is the specification of an electrical appliance that can work on  any power supply likely to be found in any country in the world. My  computer power supply has that same

# What happens when 110 volt 60 hz equipment is plugged into 220 volt 50 Hz AC outlets?

It might explode, it might blow the fuse, but it will not work  properly. But laptop power supplies seem to work from 100 v to 240  v without any switching.

# Why the standard ac frequency distribution is 50 Hz or 60 Hz and not a large figure like 500 or 1000 Hz?

The frequency of AC power is determined by the speed of the prime  mover driving the generator, be it a large hydroelectric driven  generator, a steam driven generator or a

# What is the inductive reactance of a 2 H inductor in a 60 Hz AC circuit?

2 * (60*2*pi) = 754 ohms

# What does 115 volts ac 60 hz mean?

The 115 volts is the voltage value to be used for a specific circuit. The term 60 Hz is the frequency at which a specific voltage is generated at.

# Will 145 volts AC at 60 Hz harm your home electronics?

Yes, this voltage is outside the 10% that utility company try and hold the voltage to. First thing to do is check your meter that you are using. Make sure that it is zeroed ou

# How 60 Hz converted to 50 Hz?

by using a chopping circuit.
