Why variable voltage and variable frequency control is used instead of variable voltage?
variable voltage control has some limitations as you decrease the voltage corresponding phase current will increase lead to increase of flux which lead to saturation of motor core and heating of motor to make flux constant and vary speed of motor v/f ratio need to be maintained constant
How do you use the getKey function on a TI-83 plus?
//A can be any variable and -> represents the sto(store) key function getkey->A //105 is the number of the corresponding key in this case the enter keyif A=105then*commands*end
What is accumulator in digital logic?
It is a variable or a component of a variable.
How can an individual structure member be accessed in terms of its corresponding pointer variable?
By dereferencing the pointer variable. This can be achieved in two ways: typedef struct s { int i; float f; }; void f (struct s* p) { int x = p->i; /* using pointer to member operator */ float y = (*p).f; /* using dereference operator */ } The two methods are functionally equivalent.
How you can modify an integer variable value in a function?
with an assignment: variable = value variable += value variable /= -3; ...
How do you find the missing variable in corresponding angles?
The answer depends on which variable is missing.
How can you tell if a table of values represents a function?
If all the values of the "independent" variable (x) are different then it is a function.If there are any repeats of the independent variable, the corresponding dependent variable, y, must be the same.If all the values of the "independent" variable (x) are different then it is a function.If there are any repeats of the independent variable, the corresponding dependent variable, y, must be the same.If all the values of the "independent" variable (x) are different then it is a function.If there are any repeats of the independent variable, the corresponding dependent variable, y, must be the same.If all the values of the "independent" variable (x) are different then it is a function.If there are any repeats of the independent variable, the corresponding dependent variable, y, must be the same.
The ratio of the change in the y-variable to the corresponding change in the x-variable is called the lines what '?
slope
What is the line called on a line graph that is the ratio of the change in the y-variable to the corresponding change in the x-variable?
The rise and the run.
On a line graph the ratio of the change in the y variable to the corresponding change in the x variable is called a lines what?
The rise and the run.
How can you identify a unit rate or constant of proportionality a table?
Divide an entry for one variable in the table by the corresponding entry for the other variable.
Terms that contain the same variable with corresponding variables raised to the same power?
Terms that contain the same variable is called "like terms".
What are terms that have identical variable parts with corresponding variables raised to the same power?
They are "like terms".
What is a dependent variable in research?
The dependent variable is the variable that the researcher does not control. The researcher will change one variable called the independent variable (ex. temperature, amount of sunlight, amount of food, etc.) and then observe the corresponding dependent variable (ex. reaction of organism, amount of plant growth, swimming speed, etc.)
Why variable voltage and variable frequency control is used instead of variable voltage?
variable voltage control has some limitations as you decrease the voltage corresponding phase current will increase lead to increase of flux which lead to saturation of motor core and heating of motor to make flux constant and vary speed of motor v/f ratio need to be maintained constant
What are terms that have the same variable with corresponding variables having the same exponent?
In the most arcane, technically precise jargon of higher mathematics, they are referred to as "like terms".
What is a indepentent variable?
An independent variable is the variable which you change in an experiment. you can only have 1 variable that can change in an experiment and more than one independent variable will result in an unfair experiment
