0 Ohm resistor

Yep.....
Those 0 ohm resistors are just circuit path jumpers; Kinda like a bridge over other circuit paths when they get in the way of where you need to go.
I think they use them instead of wire because they are the same size as some of the other components and the automatic insertion/soldeing equipment is already designed to handle them.

I have actually seen a resistor in an old television that had apparently overheated and the carbon inside had become crystalized. It measured 0 ohms on my multimeter. A real 0 ohm resistor!

Didn't the politicians try to redefine the value of Pi to make the math easier?

When you think about, by definition there is no no such thing as a 0 ohm " RESISTOR " I wonder who named them !
There are lots of resistors that are less than one ohm. A current shunt is less than one ohm. Used for High Current readings. I have one shunt that will give you a 50 mv reading for 500 amps

According to strict laws of physics, there is no such thing as a 0 ohm resistor.

However, from an engineering standpoint, it is possible to get "close enough" to being a 0 ohm resistor that there is effectively no difference.

In the end it depends on the context you are applying data and the level of accuracy of the results you need.

I'm not wanting to start a contest here but:
It is all a matter of perspectives. If you zero out an old analog meter to where the resistance indicated is zero and you measure a one inch long piece of welding cable it would appear as "Zero" Ohms.
Also do not discount "Super Conducting" materials. The matter of perspective also includes sub-zero temperatures and where do you place that "Zero Degree" mark. Fahrenheit, Celsius, or Kelvin.

Tallman, that isn't starting a contest with me, the examples you posted fit well within the range of possibilities within my previous post.

If you don't think your examples fit in with my post above I need you to explain why.

Some people take extreme exception to comments on a post of theirs.

???

Who is taking this "extreme exception"? What "extreme exception"?

I made a comment on the thread as a whole and incorporated different points of view. You replied with something in a way that appeared to be attempting to challenge what I said, however, it really didn't. I replied asking how what you said challenges what I said. I made no exception to anything you stated at any point. Or was it you that took "extreme exception" at something I said?

Either way I'm confused...
