What is the color code for a -10 ohm resistor

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).


Have you heard of "milliohms" ?? Most folks express would express that as 0.1ohms or in milliohms. So if you google "Resistor multipliers" you may very well come across the colour code you seek.

By definition it is not a resistor, primarily because it has no resistance.

I suppose you could call it an ass-istor?

Kill file the pathetic troll. He posts his bullshit messages on many newsgroups.

It's the same as a +10 ohm resistor but you turn it around the other way.

Come on...

Sure it is. I once knew a guy who could cook grits in 5 minutes: the laws of physics apparently ceasing to exist on his stove. And they weren't inst ant grits either. No self-respecting Southerner would use instant grits..

Like friction? Do you not remember that phone dials actually went *slower* when you tried to speed up their return by pushing the dial anti-clockwise?

Come to think of it, they may put the brown mark on the other end of the resistor.

Just buy one please and tell us all.

But you can. It was mentioned only a day or two ago in the thread on neon indicator bulbs. It is incrementally negative, mind, not averaging across the whole voltage space. And therefore called resistance rather than resistor.

Also applies to the tunnel diodes I used to play with in the 1960s which could be made to oscillate at GHz with hardly any other components.

He doesn't know the seceret handshake, so none of the cool things aren't available to him.

Isn't negative resistance a battery? After all one can measure the ESR of batteries...

That's still a positive resistance just like a resistor you add to the circuit. The only negative resistance I know of is in certain semiconductor devices and only applies over a limited range of voltage and current.

Indeed!

That would only be a negative incremental resistance. A negative resistor can't be a passive device. Power has to be added to get a true negative resistance. Line amplifier are an example of negative resistors.

Wholey (and entirely) SH*T!!

Negative Resistor:

One (any) resistor in parallel with any other resistor - the net is less than either. That, ladies and gentlemen, and children of all ages, would be a 'negative' resistor. Full stop.

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.

I built a -1K resistor once, as a school project. It was fun to play with in various circuits. Voltage dividers with gain, positive exponential time constants, things like that.
