There are many ways of making resistors
1. Carbon composition resistor is made of resistive carbon packed into a ceramic cylinder
2. Carbon film resistor has a conductive carbon film wrapped around a carbon.
3. A wire wound resistor is made with a metal wire wrapped around clay or plastic.
A resistor is then coated with paint or enamel or covered with moulded plastic to protect it.Because resistors are often too small to be written on, a standardized color-coding system is used to identify them.
