What is this?
Posted by Guy Papillon on Saturday, September 14, 2013 9:46 AM

Someone gave me some resistors he pretends to be 1k ohms.  I went to Electronicsteacher.com to learn how to read the code but I can't read this one as there is no silver or gold end.

Is this a resistor at all?

if so, what is the value?

Looks to be a 20,000 ohm resistor to me with a tolerance of 2% - verify by testing with your ohmeter ....

A fixed temperature co-efficient is only found on six band resistors ....

I goofed again.  It is BROWN not red. Embarrassed

So :  brown, black, black, brown, brown is 1k ohms.

It costed me the price of an Ohm Meter to learn. Sad

Thank you everyone for the help.

The Ohm meter needed to be in your tool box before your started doing electrical work.

So it is not a waste of $$. I am sure that you will find many uses for it in the future.

Very handy too to have with working with electrical projects.

 Hopefully you did not overpay and get a super fancy ones, the $5 or less ones from harbor Freight are perfectly adequate for model railroad work.
