Detailed explanation-1: -The colors are sorted in the order of the visible light spectrum: red (2), orange (3), yellow (4), green (5), blue (6), violet (7). Black (0) has no energy, brown (1) has a little more, white (9) has everything and grey (8) is like white, but less intense.
Detailed explanation-2: -The third band is brown, which means that the multiplier is 1. Using the formula, the resistance is thus calculated to be: As the 3-band resistor has no fourth tolerance band, the default tolerance is taken to be at 20%.
Detailed explanation-3: -The values of 3-band resistors have a tolerance of ±20% and are commonly used by hobbyists or when the resistance value is not critical. For a 1R0 (1 ) resistor with 3 bands, the colors will be brown, black and gold. The resistance value will fall between 1.2 and 0.8 .
Detailed explanation-4: -The first two bands always denote the first two digits of the resistance value in ohms. On a three or four-band resistor, the third band represents the multiplier. This multiplier will basically shift your decimal place around to change your value from mega ohms to milliohms and anywhere in between.
