How does dmm measure resistance

WebMeasuring Resistance Using a Multimeter. Series and Parallel Circuits Created by Engaging Science Labs In this lab students measure the resistance of various twinkle lights; individually at first and then in combination. They learn how to set up a multimeter as an ohmmeter and to use it for this purpose. WebMeasuring from where the voltage is going in to the resistor and then where ground is on the LED, we should see the full voltage of the circuit, expected to be around 5V. We can then see how much voltage the LED is using. …
