A 2w carbon resistor

Carbon resistors are small in size and hence their values are given using a colour code, a 2w carbon resistor. The resistors have a set of co-axial coloured rings on them. The first two bands from the end indicate the first two significant figures of the resistance in ohms. The third band indicates the decimal multiplier and the last band stands for tolerance or possible variation in percentage about the indicated values.

Carbon resistors are small in size and hence their values are given using a colour code. The resistors have a set of co-axial coloured rings on them. The first two bands from the end indicate the first two significant figures of the resistance in ohms. The third band indicates the decimal multiplier and the last band stands for tolerance or possible variation in percentage about the indicated values. For the given carbon resistor, the first three colours indicates the value of resistance and the fourth colour indicates the multiplier value. Last updated on Nov 2, Get Started. SSC Exams.

This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors. It will also calculate the minimum and maximum values based on the tolerance ratio. This calculator supports resistors with 3, 4, 5, and 6 bands. Color-coding is a method used to indicate the resistive value, tolerance, and temperature coefficient of resistors with low wattage rating because of their small size. Color bands are used because they can be easily and cheaply printed on a small electronic component. Color-coding is also used for capacitors, inductors and diodes. When the resistor body surface is large enough, as in large wattage resistors, the resistance value, tolerance, and wattage are usually printed on the body of the resistor. Surface mounted resistors SMD use another coding system that uses alphanumeric codes printed on its surface instead of color codes. The coding is defined in the international standard IEC
