But they are very inaccurate at measuring resistances in the milliohm range. The multimeter&#8217;s cable and connector resistances may be more than the resistance you are trying to measure. This video will show you a technique called four wire resistance measurement, which allows you to accurately measure resistances as low as a few milliohms using a cheap multimeter. This technique is useful whenever your circuit has high currents and you need to accurately predict the voltage drop and power loss in the wires of your circuit.<\/p>\n<style>.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }<\/style>\n<div class=\"embed-container\"><iframe src=\"https:\/\/www.youtube.com\/embed\/0vMvCVyOp9g\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\" frameborder=\"0\"><\/iframe><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Most multimeters will allow you to measure resistances in the 1 ohm to megahohm range with a high degree of accuracy.
