WebSep 23, 2024 · How to use a Multimeter Photo 1: How to Test Batteries Test battery life using a multimeter or volt-ohm meter (VOM). Analog-type multimeters use a needle and printed scales to display results from a variety of electrical tests. Function setting: Direct current (DC) voltage Scale setting: 12 volts WebApr 12, 2024 · To do this, divide the voltage applied to the winding by the resulting current. For example, if the voltage across the winding is 10 volts and the resulting current is 1 ampere, the winding resistance is 10 ohms (R = V/I). Repeat the test: To ensure accuracy, it’s a good idea to repeat the test a few times and take an average of the readings.
WebApr 25, 2024 · Using Ohm's Law The voltage (V), current (I) and resistance (R) of a circuit are related by Ohm's Law, a simple equation that states: V = I•R. Multimeters employ this law when measuring ohms, which are the units of resistance, by generating a current through the circuit by means of an internal battery. 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)
