It's a wireless compressed carbon-based resistor that has coloured rings around it to indicate its value in Ohms based on a predefined code.
its the colour of the fixed and the variable we define it by its power and name

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.
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.
those are the fixed resistor...u can't change their values..
Resistance is measured in ohms.
carbon 4 is fixed in the mitochondria and the cytoplasm
carbon
zero
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.
