However, if you change only the first or second digit colour, without changing the multiplier colour, you will need to click convert to initiate the conversion process. Note the effect of clicking on the ohm , k and M ' radio buttons'. The colour code for 560 k is given, but 560 M is outside the normal range of resistor values and generates an error message. . Suppose you want to find the colour code for a 390 ohm resistor. The program allows you to do this in two ways.
Tolerance refers to the percentage accuracy of the resistor value.
Resistors are manufactured in values which correspond to the E12 and E24 scales. Details are given in the Resistors Chapter. The program indicates whether a particular value is included in both scales, or is an E24 value only.
