Resistors and Resistance

Resistance is the opposition to current flow in an electrical circuit. Resistance is measured in ohms.

1. The clean one: Bad Boys Rob Our Young Girls But Violet Gives Willingly. Get Some Now.
2. The racist one: Black Boys Rob Our Young Girls But Violet Gives Willingly. Get Some Now.
   (At least you don't get brown and black mixed up now)
3. The really messed up one:

What resistance is a red red brown gold resistor have?

Red: 2
Red: 2
Brown: x10
Gold:

So means .

What colours make a resistor?

4: yellow
7: violet
x100: red

So yellow, violet, red

It is shown from experiment that when a current of passes through a resistor of resistance , the voltage drop across the resistor is:
