Anyone know a reverse resistor calculator?
How to read color codes from resistors.
im just already highschool but i dont understand!
The band with the metallic paint (Gold Silver etc.etc), is the 'right side' All other banding generally is done in block colour (Standardized colours used in electronics)
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# English spelling was uncorrected,# the answer is: Red=2, Red=2, BLACK=0 silver 10% +/- 22.
thanks a lot - MohammedW6
This was so helpful. I had a booklet that tried to explain it, but chose the most difficult way to explain something that it turns out is really easy! Although, as pointed out already, your answers are switched. Made me double-check my answers though, so maybe not a bad thing!
You mention that you read from left to right - but if you flip the resistor over, these directions are reveresed. How do I know which side is 'left' on a resistor? - JLoPhysics
Hey, I can answer that question for you, if you haven't found your answer quite yet. The tolerance band should be on the far right when you are looking at it. It could be Gold(5%) or Silver(10%). This means it should be xcolour, ycolour, zcolour and then your gold or silver tolerance band when you look at it. This way it is consistent and is facing the right way in order to measure the resistance when going to calculate it. As for putting your resistor in a circuit, well resistors are not polarized , therefore you can put them in any way. Good luck! - TanjotP
Hi, I think the answers are switched
The answers are switched. Using the tool provided, the first resistor is actually the second answer.
