How do you solve for variable fx in statistics?
It depends on whether fx denotes frequency times variable value or the probability generating function for the variable x.
What is the Differences between absolute frequency and relatative frequency?
The absolute frequency is the total amount of occurances of one variable. The relative frequency is the absolute frequency divided by the total amount of occurances of ALL variables.
What does an independent variable do in an experiment?
It can, but need not, affect the outcome of the experiment variable.
How does mass affect wave frequency?
lower mass = higher frequency
Is the responding variable the variable that is changed during an experiment?
it is the variable that is changed by the manipulated variable, which is to purposely change a variable to see if it has any affect. the part that has effect is the responding variable
What is the frequency of a Xylophone?
A Xylophone can create different frequencies not just one. The frequency depends on the note being played.
What changes the frequency of an xylophone?
The pitch. The higher the pitch, the higher the frequency.
What does vvvf stand for?
Variable voltage variable frequency
What is the energy savings of an electric motor when reducing the speed with a variable frequency drive?
definitly it give more efficient than variable stator voltage.............but in variable frequency ...............the frequency is not only variable....it is E/F control.because to maintain constant flux......... USUALLY THIS SPEED CONTROL IS ODOPTING IN INDUSTRIES......
What variable doesn't affect friction?
A variable that has no affect on friction is Inertia
What variable is directly proportional to frequency?
energy
Which variable is directly porportional to frequency?
energy
What are some of the leading brands in variable frequency drives?
Many companies sell variable frequency drives. ABB, GE, Eaton, Baldor, AC Tech, Honeywell, Toshiba, IDM, Hitachi, and Yaskawa are major brands that sell variable frequency drives.
Can anyone tell me how to build single phase variable frequency drive?
Single phase variable frequency drives are commercially available. Building it by an individual is complicated.
What is meant by VFD?
A variable-frequency drive (VFD) is a system for controlling the speed of a rotational or linear alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.[1][2][3] A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives.
What is the the variable you change to see how it will affect the dependent variable?
independent variable
What is the main function of Variable frequency drive?
Main function of Variable Frequency Drive is to be able to run the AC Induction motors at different speeds (by changing the frequency). The speed is a function of frequency. N - Speed. F - Frequency P - Pole N= ( 120 x F)/ P
