Resistors
'cmon, you know what a resistor is. But here is a quick guide to find out their value.

Good to know, but what's great to know is, this is the table for calculating resistor values!
| Colour | Digit | Multiplier |
|---|---|---|
| Black | 0 | 10^0 |
| Brown | 1 | 10^1 |
| Red | 2 | 10^2 |
| Orange | 3 | 10^3 |
| Yellow | 4 | 10^4 |
| Green | 5 | 10^5 |
| Blue | 6 | 10^6 |
| Violet | 7 | 10^7 |
| Grey | 8 | 10^8 |
| White | 9 | 10^9 |
Gold is 5% tolerance, and Silver is 10% tolerance.
While reading your resistor, place the Gold or Silver band to the right and read from left to right. So a Blue-Yellow-Orange-Gold would be 64 kΩ with a tolerance of +/- 5%.
This is great and all, but I know you're lazy and you're not learning this today. So here's the link to a graphical resistance calculator: Link
