Resistor colour codes - Trevor Briggs - 16/06/2015

After the last club night I offered to put on the web site a brief explanation of how to read the resistor colour code, so here it is

The colour bands used are as follows;-

0             Black
1             Brown
2             Red
3             Orange
4             Yellow
5             Green
6             Blue
7             Violet
8             Grey
9             White

There are also two metallic colours which I will get to later. The value is read with the metallic colour to the right as follows,

1st band gives the first digit
2nd band gives the second digit
3rd band gives the number of noughts
4th band  metallic, gold or silver

So the colours on your resistor may be brown, black, red, gold

This gives a value – brown=1
                                 Black =0
                                 Red = 2 noughts

So the value of your resistor is 1000 ohms, the last band, gold, gives the tolerance in this instance 5%, silver would give a tolerance of 10%, that is + or – 5% or 10% of the value of the resistor.

I hope that is clear and will be of use to folk trying to get to grips with  LED lighting.
