Try this mnemonic if you are trying to remember the resistor color codes:
| Bad | (0) Black | |||
| Beer | (1) Brown | |||
| Rots | (2) Red | |||
| Our | (3) Orange | |||
| Young | (4) Yellow | |||
| Guts | (5) Green | |||
| But | (6) Blue | |||
| Vodka | (7) Violet | |||
| Goes | (8) Grey | |||
| Well | (9) White | |||
| (0.1) Gold | ||||
| (0.01) Silver |
Note: If you’re missing a tolerance band that implies that the tolerance is 20%.
Which end do you start reading the color bands?
There are usually two ways:
1) If one of the bands at the end of the sequence is further apart then that is the tolerance band – start from the opposite end.
2) If all the bands are closer to one side of the resistor then start from that end – the tolerance band is the last one your read.
