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.
Colors
Here is the table with the colors and numbers. As you can see they are:
- 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%
Calculator
Resistor color code calculator
If you are too lazy to think about colors and digits and mat ... this is for you :) :D
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 :)
Exercises
Now some exercises :)
Try to calculate resistors' values from third and forth picture.
Answers are below.
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%.
It's your answer? I hope so :)
