How to Measure Resistance with a Digital Multimeter

WebWe know from Ohm’s Law that resistance is equal to voltage divided by current (R = E/I). Thus, we should be able to determine the resistance of the subject component if we measure the current going through it and the voltage dropped across it: Current is the same at all points in the circuit, because it is a series loop.

WebSince the voltmeter has a range down to 0.1 mV, it can measure down to 0.01 ohm. To increase the sensitivity, you can purchase a more sensitive voltmeter or use a lower resistor value. Because resistors are sensitive to temperature changes, the power rating needs to be higher. Ask Question Participated in the Pocket-Sized Contest View Contest WebStep 1: Select a suitably low-resistance specimen to use in this experiment. One suggestion is to use the electromagnet coil specified in a previous experiment or a spool of wire where both ends may be accessed. Step 2: Measure the resistance directly using the ohmmeter function. We will compare this 2-wire measurement value with the value we ...
