This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma.

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.
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.
Why inductor is only used for ac power supply?
Because inductance is only related to alternating current. Direct current doesn't induce eletrical current on a secondary coil placed on a primary coil, because there is no frequency generated by direct current, and all you get is a single electrical current flowing through the wire without interfering with a coil placed near to the primary coil. What makes all the difference is the cycles per second that only alternating current can generate.
How many times per second does the alternating current generated at large power generator reverse directions?

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 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.
Number of complete cycles in a second is a whole number where as it is not?
The frequency does not have to be a whole number. 3 cycles in two seconds is equivalent to 1.5 cycles per second so the frequency is 1.5 Hertz. That is not a whole number!
How many alternations make up one cycle of an alternating current?
Frequency in Hertz is a count of cycles per second. So at 60Hz, there are 60 cycles per second. This means there are (60 cycles per second x 60 seconds) = 3600 cycles per minute.
Is 1 Hz is equal to 1 wavelength passing a stationary point in 1 minute?
1 Hz is the number of complete cycles of a wave in one second. If after 1 second there is 5 complete cycles of the wave, that means the frequency is 5 Hz.
Is 1 Hz equal to 1 wavelength passing a stationary point in 1 minute?
1 Hz is the number of complete cycles of a wave in one second. If after 1 second there is 5 complete cycles of the wave, that means the frequency is 5 Hz.
What is the number of crests and troughs that pass a point per second?
That is twice the frequency. Frequency is equal to the number of complete cycles which pass a point per second.
Electricity with a frequency measured in cycles per second or Hertz and consists of alternating sinusoidal waves is known as?
ac
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.
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 the number of wave or cycles per second called?
The number of waves or cycles per second is called frequency, typically measured in Hertz (Hz).
What is power Hz?
The term Hz stands for Hertz which means cycles per second; the normal alternating current is 60 Hz, it alternates 60 times per second.
What is the number of cycles per second of a wave?
The number of cycles per second of a wave is typically referred to as its frequency and is measured in Hertz (Hz). A frequency of 1 Hz means one cycle per second.
