This chart describes the value and the rate of tolerance of different colours in the different types of resistance bands. Resistor Colour Code calculatorįigure 2: Resistor Colour Code calculator The first three bands represent the digits of the resistance power, the fourth colour band signifies the multiplication factor, the fifth colour band represents the rate of tolerance power and the last colour band stands for the temperature coefficient. The 6-Band Resistors is made with six different colour codes (Ashok, 2021). This resistor denotes the temperature coefficient that generally indicates the reliability of the electric flow. The last fourth band of colour denotes the rate of multiplier and the last colour band of the resistance signifies the rate of voltage tolerance (Chowdhury & Kumar, 2020). Among them, the first three bands represent the digits of the resistance power. The tolerance power of this resistor is below 20%.ĥ-Band Resistors includes five different colour bands. In this type of resistor, the first two bands of colour defined the resistance value, the third colour band represents the rate of multipliers, and the last band of colour stands for the rate of electricity tolerance. 4-Band Resistors is another type of resistor in which three bands are located on the left side and the other one is in the right side (Chowdhury & Kumar, 2020). The value of the resistor differs from 1.2 to 0.8 ohms. 3-Band Resistors comprises a lower resistance value and in this resistor, the colour of the three bands is brown, black as well as gold. There are different types of resistors used in electric circuit construction. The identification process of Resistor Colour Codes Among the three numbers, the first two numbers stand for the resistance value rate and the last colour band is denoted as a multiplier. The number bands of the resistor body presented with the variation of three to six numbers. This can be seen in a large power resistor. The electric designers print the rate of tolerance, resistance value as well as wattage rating on the body of a resistor in numerical or alphabetical form. The colour band of the resistor is called resistor colour code. The resistor is a tiny electric body having printed with many colours on the body to denote the different values of electrical resistance.
