Abbrevations Electronics Dictonary Components Basic Electronics Digital Electronics Fiber Optic Demo's | RESISTORS COLOUR CODE: Ignore the colour of the resistor body. The band nearest the wire lead gives the value of the first digit. e.g Brown = 1. The next band gives the value of the next digit e.g. red = 2 The third band gives the number of zeros which follows the two digits.e.g. orange = 3 zeros = 000. Therefore a resistor with brown, red, orange bands would have a value of 12000 ohms. This resistor has a value of 2,700,000 ohms. A green blue black resistor would be 56 ohms. (black indicates that there are no zeros). Black = 0 If the third band is silver then divide the value of the first two digits by 100, if gold divide by 10. The fourth band indicates the tolerance. brown 1% If there is a fifth pink band this indicates a high stability resistor. |
