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.
A carbon composition resistor is made from a compound of carbon graphite and resin bonding material. This type of resistor has a cylindrical shape and is used for applications requiring high stability and low noise levels.
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
