Hz is short for Hertz, which is the international standard (SI) unit of frequency of an alternating current (AC) voltage. 50Hz means the voltage alternates 50 times per second, 60Hz obviously means 60 times/sec. 60Hz is the normal frequency of the incoming power lines in North America, while 50Hz is seen in many European countries. While convertors exist to use electric devices on a different voltage, convertors generally are not available to use 50Hz devices on a 60Hz power grid, or vice-versa. While some devices can be used on either, many others will not work or may even be damaged. Check with the manufacturer to be sure. Incidentally, since the unit of Hertz is named after the German physicist Heinrich Hertz, it is customary to capitalize the H. So 60Hz is considered correct, while 60hz is not.
One cycle of a 60 Hz AC (alternating current) waveform takes 1/60th of a second to complete. This means that the waveform goes through one complete cycle— from zero to its maximum positive value, back through zero to its maximum negative value, and back to zero— in 1/60th of a second.

Which major phase takes up the most time in a normal gait cycle?
The stance phase typically takes up the most time in a normal gait cycle, accounting for about 60% of the entire cycle.
How will you get the disk rotation time?
Disk rotation time can be calculated using the formula: Rotation time = (1 / RPM) * 60 seconds. RPM stands for revolutions per minute, which indicates how many times the disk spins in one minute. By taking the reciprocal of the RPM and multiplying it by 60 seconds, you can determine the time it takes for one complete rotation of the disk.
What is the efficiency of the Krebs cycle?
The efficiency of the Krebs cycle in terms of converting glucose into ATP is around 60%. This means that for every molecule of glucose that enters the cycle, about 60% of the energy is captured in the form of ATP. The rest of the energy is lost as heat.
How many eggs can snakes have at one time?
It depends on the species - anywhere from 10 to 60 !
What is ac frequency?
AC frequency refers to the number of complete cycles of alternating current that occur in one second. It is measured in Hertz (Hz) and determines the rate at which the direction of the current changes. In most countries, the standard AC frequency for power distribution is 50 or 60 Hz.
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 does time relate to degrees in an AC sine wave?
One cycle of the sine wave is equal to 360 degrees. In US the frequency of power is typically 60 Hz and hence one cycle is 1/60 of a second. Therefore you can calculate the degrees at any instant of time. If at zero degrees the voltage amplitude is zero, then at 90 degrees,which is 1/4 cycle, wave is at peak voltage. At 180 degrees it is at 1/2 cycle and zero voltage and then at 270 degrees it is 3/4 of the cycle and a peak negative voltage. Finally at 360 degrees the cycle is complete and the voltage is again zero.
How many seconds are there in one cycle as it pertains to 60 cycles?
There is one second in 60 cycles. So 5 cycles is equal to about 0.012 seconds or 12 milliseconds.AnswerThe periodic time is the reciprocal of frequency. So the answer to your question is 1/60 s or 16.67 ms.
What is the phase of a sine wave which is offset one sixth of a cycle with respect to time zero?
1/6th of a cycle is 60 degrees or (pi/3) radians.
The period of an ac wave is?
period is the time duration of one cycle of the waveform, and is measured in seconds/cycle. AC power at 50 Hz will have a period of 1/50 = 0.02 seconds/cycle. A 60 Hz power system has a period of 1/60 = 0.016667 seconds/cycle
A phase that takes about 50-60 percent of the total time to complete mitosis?
The phase that takes about 50-60 percent of the total time to complete mitosis is typically the interphase. Interphase is the longest phase of the cell cycle where the cell grows, carries out normal cellular functions, and duplicates its DNA in preparation for cell division.
What is one second?
A unit of "time" invented by humans which is a measure equal to 1/60 of one "minute", which is equal to 1/60 of one "hour", which is equal to 1/24 of one complete "day". The list goes on..
What is the average percentage of marathon runners complete a marathon?
60 percent of the time they complete it everytime
The required output of an assembly line is 3000 units in an 8 hour shirf the required cycle time for the line is?
It must cycle 3000 times in 8 hours. 8/3000 hr/cycle * 60 minutes/hr * 60 seconds/minute = 28800/3000 seconds/cycle = 9.6 seconds/cycle
Which major phase takes up the most time in a normal gait cycle?
The stance phase typically takes up the most time in a normal gait cycle, accounting for about 60% of the entire cycle.
This planet requires 59-60 earth days to complete one rotation on its axis?
The planet takes 59-60 Earth days to complete one full rotation on its axis, which means its day is equivalent to that duration. This longer day-night cycle is due to the planet's slower rotation speed compared to Earth's.
What is the length of the cardiac cycle if the heart rate is 80 beats per minute?
To find your answer, your first step is to divide the time (in this case a minute...a minute equals sixty (60) seconds) by the heart rate (e.g. 80 beats). So---60 divided by 80 will give you 0.75 seconds. Your answer will justify the time/length of the cardiac cycle.
