How To Read A Resistor
identify the first band, write down the number associated with that color; in this picture it shows a 4 band resistor, first color is yellow and that's '4'.
now the next color is purple, so write down a '7' next to the four.
Now the third color is orange or the 'multiplier exponent' band and orange has three zeros and you see a big gap and next to it the tolerance is gold, that's ±5%
so we have '47x103
