The metric unit of frequency is the hertz (Hz), which is one cycle per second. It is named for German physicist Heinrich Rudolf Hertz (1857-1894).

What does the unit hertz refer to in an AC circuit?
It refers to the number of cycles (frequency) of the a/c source per second; 1Hz=1 complete cycle per second.
How many cycles in 60 Hz?
A cycle is one complete revolution of the sine wave. Hertz is the frequency of the alternating current, how many complete cycles per second. 60 Hertz would have 60 cycles each second.
How is frequency measured on an oscilloscope?
Frequency is, in general, measured on an oscilloscope by looking at the display and making a small calculation. By determining the number of "units" a cycle of an observed wave takes up on the screen and incorporating the sweep rate as set by the operator, you can find the frequency. To do this, look at the signal. Increase the vertical sensitivity to make the wave "take up most of the screen" without chopping any of its amplitude off. Center the signal vertically in the display. Then adjust the sweep rate to get more than one but less than two complete cycles of the wave on the display. Now count the number of "units" on the graticule from the "start" to the "end" of one complete cycle. Lastly, take the horizontal sweep rate from the dial and apply that to the number of units you counted on the graticule. The sweep rate will be in time per graticule unit. Multiply this by the number of units that you counted for a cycle. You'll calculate the total time per cycle from this information. What you will actually get is the period of the wave. It will be the time it takes for one complete cycle of the wave. The period of the wave is the time per cycle of the wave. With the period, you can simply invert it to find the frequency in cycles per second (Hertz). Seconds per cycle inverted is cycles per second.
How much current flows through a circuit if 2 coulombs of charge flows each second?
Current in amperes is coulombs per second, so 2 coulombs per second is 2 amperes.
Definition of voltage?
Voltage is electrical pressure, in joules per coulomb. One volt across one ohm will yield a current of one ampere, which is coulombs per second. One volt, producing one ampere, will yield one watt, which is joules per second.
What is another term for cycle per second?
Hertz (Hz) is a term for cycles per second.
How many mega hertz in a cycle per second?
Another name for Hertz is cycles per second. So a Megahertz is 1 million cycles per second.
50 hertz is what period of vibration?
50. Hertz is the same as cycles per second.
What is another name for cycles per second?
Hertz
Another name for cycles per second?
C.p.s?
A unit of one cycle per second?
For waves the unit of one wave cycle per second is Hertz
Which is bigger hertz or cycle per second?
Hertz is the present-day name for the measurement once called cycles per second. They're the same thing.
Are cycle per second the amount of waves per second?
Yes, a cycle is from start to finish of a wave function (until it repeats again)
A megahertz is what cycle per second?
One Megahertz is one million cycles per second.
Number of waves per second?
One Hertz equals one cycle per second.
How many cycle per second?
There can be any number. Cycles per second are referred to as Hertz
What is a unit of measure for frequency consisting of a wave or cycle per second?
Hertz (Hz) is the SI unit of frequency, equal to one cycle per second.
