The value of the resistor is marked on the body using colors. Every color is different number and you can remember these numbers or you can just use the table on next step. OR there are much resistor calculators that you can use. It's for the laziest people :D . However it's your decision ,and I will show you all ways to calculate resistor value.

## Step 1: Colors

**BLACK: 0****BROWN: 1****RED: 2****ORANGE: 3****YELLOW: 4****GREEN: 5****BLUE: 6****VIOLET: 7****GREY: 8****WHITE: 9**

**BLACK: 1****BROWN: 10****RED: 100****ORANGE: 1000****YELLOW: 10000****GREEN: 100000****BLUE: 1000000****GOLD: 0.1****SILVER: 0.01**

**BROWN: 1%****RED: 2%****GOLD: 5%****SILVER: 10%****NOTHING: 20%**

## Step 2: Calculator

Resistor color code calculator

If you are too lazy to think about colors and digits and mat ... this is for you :) :D

## Step 3: Examples

Exemple: if first color is RED ,second is RED ,third is BLACK and the last is SILVER it means:

RED - 2 -- RED - 2 -- YELLOW - x10000 -- SILVER - 10% so...

2 2 0000 +/- 10% * 2 2 0000 so... :D

220000 +/- 22000

This is 220 000 Ohm or 220 kOhm

or 220 000 - 22 000 Ohm or 220 - 22 kOhm

or 220 000 + 22 000 Ohm or 220 + 22 kOhm

Hope you got it :)

## Step 4: Exercises

Now some exercises :)

Try to calculate these resistors' values.

Answers are on the next step.

## Step 5: Answers

The first one is : 11000 = 11k ohms

The second one is : 1000 = 1k ohms

The both are with gold color for the tolerance ,it means 5%.

Your answer? I hope so :)
