Resistors


Colour code for resistors
From this chart we can calculate the resistance of a resistor ....
We also can measure their resistance with a Ohm meter or ohm setting on a multimeter.
Colour bands are calulated as the first band is 1st digit , 2nd band is the second digit, 3rd band depending on the number of bands on the resistor could be the 3rd digit if there are 5 bands or only 4 bands then it would be the multiplier... then the next one would be the tolarance percentage of the resistor .
