Question

How to find the value of the resistor without using multimeter

Answer 1

Explanation:

So this is a trivial but frustrating issue I’ve come across. I have two 5 band resistors and I am having a hard time differentiating the tolerance band.

I don’t have a multimeter on me and I don’t know if these are 1k (Brown black black brown brown) or 110ohms (Brown brown black black brown). Am I being completely oblivious to something?

Edit: I do know that the tolerance band is supposed to be at the end with the largest band spacing, but it looks equidistant to me.

Answer 2

Answer:

Take a watch and measure how long it takes for the LED to turn on. Compare with other known resistors. Start reading from the end of the resistor where the color bands are closer together. In the picture, that appears to be brown-black-black-brown, brown
