What is the color code for a -10 ohm resistor.
That's a NEGATIVE 10 ohm resistor, not a standard (positive) 10 ohm
brown-black-black resistor. (Thats 10 ohms below zero ohms).

Are you perhaps thinking of reactance, which is some value multipled
by sqrt(-1)? Inductors and capacitors are normally not marked with
their reactance values because it varies with frequency.

Another possibility is that you have inserted the battery in your
ohms-guesser backwards, and are therefore producing negative
resistance readings. If not the battery, then perhaps the meter leads
have been reversed.
