A VMD … 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.

WebTurn the dial to Continuity Test mode. It will likely share a spot on the dial with one or more functions, usually resistance (Ω). With the test probes separated, the multimeter’s display may show OL and Ω. If required, press the continuity button. First insert the black test lead into the COM jack. Then insert the red lead into the VΩ jack. WebIt appears that the actual resistance of your wire is 1025 - 1030 ohms (perhaps poor contact on your probes accounts for the variation). This will display most accurately on the 2K range. On the 20 K range, the last digit falls off the end of the display, so you see 1.02 or 1.03 K.

WebStep 1: Select a suitably low-resistance specimen to use in this experiment.
