Homework Statement


Its a general question asking which method of measuring resistance (a 5 ohm resistor in a simple circuit) has greatest precision. The first method I varied voltage from about 5V to 10V, then measured the current each time, then averaged that current and calculated resistance. The other method was remove resistor from circuit then direct measurement of the resistance using multi meter.
The question asks "Which method of measuring the resistance of small resistances is capable of greater precision?"
I am not really understanding what is being asked ..thanks for any help

To understand what is being asked, you first need to do some research and figure out how the multimeter that you used measures the resistance that you connect to it. Then you need to compare its method with yours. I can already see a problem with your method. Think how resistance is defined by Ohm's law.

For future reference: Please show your work and calculations. Merely talking about them is not sufficient.
