1 Appendix This appendix contains numerous pieces of information that you will find useful in constructing the circuits in the laboratories. Keep this appendix handy for reference in the laboratory sessions. Resistor Colour Codes How can you tell the value of a resistor, it only has coloured lines on it, but no value? The coloured lines tell you the value of the resistor. There should be 4 lines on each resistor, and their colours allow us to determine the value of the resistor. Once of these lines should be either gold or silver, this is the fourth line and gives the tolerance of the resistor (how accurate its value is). The other three lines give the value of the resister. The first two lines give the first two significant digits of the resistor’s value and the third line gives the magnitude of the value (the power of ten the first two digits are multiplied by). The following table gives the colour code used for these three lines. Colour Value Multiplier Black 0 Brown 1 X10 Red 2 X100 Orange 3 X 1k X1
