Method of finding the value of the through-hole resistor
• Digit digit multiplier tolerance (for 4 band resistor )
• Digit digit digit multiplier tolerance (for 5 band resistor)
Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4.7or 4k7.
Green Grey Black Red Brown=5 8 0 2 = 680×102 =58k Ohms
Tolerance: ±1%
If A resistor is colored green–red–gold–silver, then its value is 5.2 Ω and tolerance of +/- 10%.
A resistor-colored Brown–Green–Grey–Silver-Red would be 1.58 Ω with a tolerance of +/- 2%.
