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.
