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 :)
