A resistor of 100 ohms 20 would be expected to have a value between 80 and 120 ohms.

What is the value of this resistor. As shown above a carbon composition resistor can have 4 to 6 bands. Select the first 3 or 4 bands for 20 10 or 5 resistors and all 5 bands for precision 2 or less 5 band resistors. Multiply the two digit number by the multiplier.

Resistance value calculation using multimeter. Resistor color code calculator. A resistor is a device that opposes the flow of electrical current.

The bigger the value of a resistor the more it opposes the current flow. A sensible spacing e6 is used for 20 components. The resistance value of a resistor can be calculated using the resistor color bands.

A 5 band resistor is more precise compared to a 4 band type because of the inclusion of a third significant digit. Resistor tolerance is a measure of the resistors variation from the specified resistive value and is a consequence of the manufacturing process and is expressed as a percentage of its nominal or preferred value. This gives you the nominal value of the resistor in ohms.

Resistance value calculation using color code. Its e6 neighbors are 68 5482 and 150 120180 ohms. The resistance value is displayed on the field below together with the tolerance and the temperature coefficient.

E48 for 2 e96 for 1. Resistance value calculation using color code. More online conversion calculators at digi key.

This helps the supplier to limit the number of different values that have to be produced or kept in stock. The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. In the resistor shown in the preceding figure the two digit number is 47 and the multiplier is 10 so the nominal value is an easy way to multiply a whole number by a power of 10 that is 10 0.

The standardization of resistor values serves several important purposes. The value of a resistor is given in ohms and is often referred to as its resistance. When manufacturers produce resistors with different resistance values these end up approximately equally spaced on a logarithmic scale.

The calculator above will display the value the tolerance and performs a simple check to verify if the calculated resistance matches one of the eia standard values. E192 for 05 or better. The resistance value of a resistor can be calculated using the following two methods.
