To limit the current
A variable resistor means that the resistance can be varied, usually by using a slide. A fixed resistor can not be varied.
Resistance is measured in ohms.
Hi, where there is no need of changing the value of resistor then why do you place variable resistor instead a fixed resistor. After all the selection of resistor depends on the cause of use in application. by the way wide range of resistor values are avilable in the market. if the application requires tuning operation then variable resistor is need to be mounted. nothing is mandatory unless the application requires.

It resist the flow of current according to the resistance value.
fixed value, stepped or tapped, variable
its the colour of the fixed and the variable we define it by its power and name
The resistance that controls a heater motor in the electric system .
symbols of fixed resistors
Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.

those are the fixed resistor...u can't change their values..
Resistance is measured in ohms.
