CROSS-REFERENCES Lessons In Electric Circuits, Volume 1, chapter 8: “DC Metering Circuits” LEARNING OBJECTIVES SCHEMATIC DIAGRAM ILLUSTRATION INSTRUCTIONS Although this experiment is best performed with two meters, and indeed is shown as such in the schematic diagram and illustration, one multimeter is sufficient.
Most ohmmeters operate on the principle of applying a small voltage across an unknown resistance (R) and inferring resistance from the amount of current drawn by it.
Being part of the measurement circuit, the test leads may contain more resistance than the resistance of the test specimen, incurring significant measurement error by their presence: One solution is called the Kelvin, or 4-wire, resistance measurement method.
It involves the use of an ammeter and voltmeter, determining specimen resistance by Ohm’s Law calculation.
The quotient will be equal to the specimen’s resistance in ohms.
The new HTML5 sims can run on i Pads and Chromebooks, as well as PC, Mac, and Linux systems.
Except in special cases such as the megger, both the voltage and current quantities employed by the meter are quite small.
This presents a problem for measurement of low resistances, as a low resistance specimen may be of much smaller resistance value than the meter circuitry itself.
