suggestion for Lasersbee: take a Tylenol or something - you're just provoking normal defensiveness.

suggestion for Milan: stop defending yourself - you're just encouraging him.

To the point: the voltage-across-resistor is more accurate most of the time. That's because inside the multimeter, it actually has a resistor... it measures th voltage across that resistor... and depending on what range it is on, that resistance in series with your circuit will affect how much current the circuit draws - thus affecting the very thing it is supposed to be measuring. By using a 1-ohm resistor you are putting a known amount of resistance in the circuit, a small amount.

ROFL.... Thanks DanQ... I needed that....  Just took one... ;D ;D ;D a little levity never hurts...

funny... I was just thinking about levitation - interesting, how they are so alike...  :-?

I feel sorry for laserbee's full stop key, thats the real victim in all this

That quote was directed at Milan... not you Kendon...

It has been edited...

that happened way too often in this rather heated thread... :

//edit: before someone gets it wrong, it happened for me too. i'm not trying to offend anyone!
