Say I have a 20 ohm resistor with a tolerance of 5%. What does it mean to have a tolerance of 5%??
Thanks

Just one more question
Say you put 2 of these resistors in series. The resistance will jump to 40 ohms but what happens to the tolerance? Will it double or stay the same?

You know that the smallest you can get is 19+19 Ohms, and the largest is 21+21 Ohms. What tolerance does that indicate. Now do it for the parallel resistor case.... Do you get a similar or different answer...?
