Decide which band is the first band. Heres how you use the color code to figure out the nominal value of the resistor refer to the figure.

Solved Derive The General Equation For The Output Voltage

The resistive range of a power resistor ranges from less than 1w r005 up to only 100kw as larger resistance values would require fine gauge wire that would easily fail.

General resistor values. Compare the ends of the resistor. Standard resistor values in 1952 the iec international electrotechnical commission decided to define the resistance and tolerance values into a norm to ease the mass manufacturing of resistors. Decoding the nominal value of a resistor.

Standard resistor values 5 10 10 100 10k 10k 100k 10m 11 11 110 11k 11k 110k 11m 12 12 120 12k 12k 120k 12m 13 13 130 13k 13k 130k 13m. Round the results to the proper number of significant figures three for 1 and 2 two for 5 and 10. E3 e6 e12 e24 e48 e96 to simplify resistor manufacture handling purchase and circuit design resistor values are arranged into standard resistor values known as the e series.

The resistance value of wirewound resistors is very low low ohmic values compared to the carbon or metal film types. R d10 in i 0. The general formula to calculate standard resistor values is given below.

These are referred to as preferred values or e series and they are published in standard iec 600631963. Usually the colored band at one end is closer to that end than is the colored band at the other end. As the chart at the right shows created in excel plotting the values on a logarithmic scale results in a straight line due to the exponential in the equation.

The results are then rounded to the proper number of significant figures 3 for 1 and 2 2 for 5. Standard resistor values are calculated using the simple formula given below.
