Webdmm-futureworks.com WebHow it works. When you select the resistance function of your DMM, it will supply a small DC voltage on its leads so that a current can flow through the unknown resistor, it will adjust this current to some convenient value and by reading the voltage, the current and using Ohm's law it will display the corresponding resistance.

So when you see 1.500 volts, it’s really 1.500 milliseconds, relabelled. It works out very well because capacitors with a constant current going into them charge up a predic...

WebAs shown in Figure 1, a test current - typically a few mA - is sent out by the multimeter and the internal DVM (digital voltmeter) module measures the voltage drop across the component. Ideally you take measurements with the components out of circuit. You must be careful when measuring components in a PCB. Web19 de out. de 2014 · Technically, voltage cannot be drawn because its a potential energy between 2 points like gravitational pull. Thus, when the multimeter probes is placed on the resistor, it would draw the full voltage of the battery, the thing that is drawn would be current which causes the galvanometer on the multimeter to deflect.
