The AC power distribution system has specific frequency Why is this frequency 50 hertz in some parts and 60 hertz in other parts of the world?

When electricity was first being used, there were only local power lines which produced a wide variety of frequencies and voltages. Light bulbs were about the only electrical equipment that would be usable on every system. An electric motor would run at different speeds in different towns. As the grids grew and interconnected, things had to be standardized. No one in the Americas needed to coordinate with anyone in Europe or Asia because they would NEVER be interconnected! So here, we developed a standard of 120V/60H while they settled on 240V/50H.

What is the unit of frequency in CGS system?
hertz
What is the measurement of frequency of a system bus?
Frequency is measured in Hertz, or cycles per second.
Which of the following is the correct unit of frequency?
Frequency is measured in Hertz. Its symbol is Hz.
What are Hertz used to measure?
Hertz is used to measure frequency ie the number of times per second that something happens. Its commonest uses are to measure the number of oscillations/sec of electric currents or radio waves and the processing speed of computers.
What is the measurement of frequency of a system bus and CPU?
The frequency of activity on a motherboard is measured in megahertz (MHz), or one million cycles per second. The processor operates at a much higher frequency than other components in the system, and its activitiy is measured in gigahertz (GHz), or one billion cycles per second.
What it means for a wave to have a frequency of hertz?
hertz is what frequency waves are measured in.
Which property is expressed in units of hertz?
dynamic frequency, which is cycles per second, or Hertz
What unit is sound frequency measured in?
Frequency is measured in hertz. Cycles per second.
What are the standard units for frequency?
hertz Hz
Frequency in hertz?
it is named after the scientist hertz
Hertz Hz is the unit used to measure a wave's?
Hertz means cycles per second. That is its' frequency.
The number of cycles per second is called?
Frequency, which is measured in Hertz (Hz)
