Measure voltage drop across resistor using voltmeter?

How to measure voltage drop across a resistor using a voltmeter?
[ATTACH]222000[/ATTACH]

do I put the red pin from the voltmeter on point 1 and black pin on point 2?

or

do I need to find a ground and put red pin on point 1, black pin on ground, and do the same for point 2, and take the difference in voltage?

One pin from voltmeter to point 1 and the other pin to point 2. That will measure the difference in voltage between the two points a.k.a. voltage drop. Both methods should give you the same result actually. But it is probably easier to measure on each point at the same time.

Edit: A bit late I see. Better late than never incase someone asks the same question.
