How do i use an ohmmeter

WebJan 10, 2024 · An ohmmeter works on the basis that when an ohmmeter applies current to a circuit or component, it measures the resultant voltage and calculates a resistance value using the formula for Ohm’s law V = IR. We can also use an analog and digital multimeter to measure resistance. Contents show When Was the Ohmmeter Invented? WebApr 17, 2009 · Ohms law states Voltage (EMF) / Current (flow of electrons) = Resistance (Ohms) Ex. 10 volts / 1 amp = 10 ohms of resistance. You can move the formula around to solve for any 1 if you know the other 2. And you can throw in Power (Watts) to solve for other values Power (watts) = I^2 (current squared) * R (ohms) or P = I * E (voltage)
