it doesnt have to be kept constant but is convenient
little synchronous motors in clocks
transformer core materials depend on frequency
airplanes use 400hz for less iron and weight in Transformers
higher frequencies conductors are hollow and silver plated or clad
easier to synchronize generators if they are at the same frequency

Why steam turbine speed is kept constant in power plants?
Well, the steam turbbine is most likely connected to an A/C generator which gives off the same frequency as the grid, so by running the turbine on a fixed frequency you don't have to condition the electricity before it can be released onto the grid.
What means the variable that must be kept constant?
What variables must be kept constant
How wavelenth of waves traveling with speed would change if the frecuency of the weaves icreased?
Velocity of wave = Frequency X Wavelength So if Velocity of the wave is kept constant, then Frequency of the wave is inversely proportional to it's wavelength i.e increase in frequency means decreases in Wavelength.
How many variables are kept constant in a experiment?
All variables except one, the experimental variable, are kept constant in an experiment.
What factor is kept constant?
The factor that is kept constant in an experiment is called the controlled variable. It is important to keep this variable constant to accurately measure the effect of the independent variable on the dependent variable.
When frequency and voltage of an RC coupled amplifier are kept constant then what happens to the amplitude of output?
There is insufficient information in the question to answer it. Something has to change if you are asking what happens to amplitude, but you did not provide that "something". Please restate the question.
Boyle's law states that the volume of a gas is inversely propertional to its pressure if the?
Temperature and amount (number of moles) is kept constant.
Which of the following occur as a result of decreasing the heat energy of a gas?
If pressure is kept constant, the volume will decrease.If volume is kept constant, the pressure will decrease.
Sentence of constant?
His constant pace was one thing that kept him ahead of everyone. This is a sample sentence using constant.
What is a experimental constant?
There are potential variables that are kept constant for each trial in a set of trials.
Where is the perfect meter kept?
Its kept in a museum in Paris, inside a glass case with the temperature inside the case kept the constant.
Why should a prime mover's speed be kept constant?
As you asked the question and it was added it to the electrical category I am presuming that you are talking about electrical generation. The prime mover has to be kept at a constant speed. The speed of the prime mover governs the frequency of the voltage generated. As the load increases the engine will start to slow down. The engine's speed governor senses this drop in RPM, hence the drop in frequency, and increases the fuel supply to the engine by advancing the diesel engine's fuel rack. This action increases the engine speed and brings the generated frequency back to the required system frequency.Also as the load increases, the output voltage will start to decrease. The output voltage is controlled by the generator's voltage regulator. When the decrease in voltage is sensed by the voltage regulator, it increases the generator's field excitation voltage which will bring the voltage back to the required system voltage.These actions are going on continuously, balancing each other all the time the engine is running and the generator is producing an output voltage.
