Where, gray = 8, brown = 1 and black = 0. List the color bands of the resistors below Where, blue = 6, black = 0 and yellow = 4. Privis Electrical Engineering Company designed the resistor which has the band colors of blue, black and yellow. Thus, a 200 resistor with a tolerance of 5% can have an acceptable range of values from a minimum of 190Ω to a maximum of 210Ω. If the resistor have four band colors, the fourth band indicates the percent tolerance but if it have five band colors, fifth band indicates the percentage tolerance.Ī 5% tolerance means that the actual resistance value is within ±5% of the color-coded value.The third band is the multiplier if the resistor have four band colors else the forth would be the multiplier if it is five band colors.The second band is the second digit of the resistance value.If it is not clear which is the banded end, start from the end that does not begin with a gold or silver band. The first band is the first digit of the resistance value. Start with the band closest to one end of the resistor.Four color band resistor (a) and five color band resistor (b). The bands are always closer to one end.įigure 19. This color-code band system is shown in Figure 19, and the color code is listed in Table 7. Every resistor has value and the value can be known by their colors or using ohmmeter.įixed resistors with value tolerances of 5% or 10% are color coded with four bands to indicate the resistance value and the tolerance. The ability of resistor to oppose current flowing in the circuit is called Resistance. In electrical circuits, resistor cannot be ignore because resistor help engineers and technicians to regulate current and stabilized current for specific load. Resistor is the electrical component that oppose electric current flowing in the circuit.
