However, upon closer inspection it is seen that nothing is lost at all, because the voltmeter’s wires carry miniscule current. Thus, those long lengths of wire connecting the voltmeter across the 4-wire Resistance Measurement | DC Circuits | Electronics wwwboutcircuits››Vol. VI - Experiments›DC CircuitsOne 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. A current is passed through the unknown resistance and measured.
