WebIt’s basically Ohms Law. Check this out. Since we know voltage drops and amperage can be accurately measured (unlike IR, depending on who/what you ask) we can calculate IR readings with that information. Say you have an amp draw of 250 amps. Say you’re running 8S. Say you have a voltage drop of 10 volts at 250 amps. Now we can calculate IR. WebTo measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity, capacitance or diode; see illustration below). desserts to make with frozen fruit
