How do you test a resistor with a multimeter
Web6) With the multi-meter set to AC voltage measure the Voltage between terminals of both the Resistor (VR) and the inductor (VL). 7) Move the potentiometer until the read of VR equals VL. See pictures (readings of 9.22V and 9.17V) 8) Turn off the power 9) Disconnect the potentiometer gently so you don't change its value. WebJan 15, 2024 · Using a Multimeter, you can Check if the switch (or push button) is properly working or not. Measure the amount of current flowing through a device, like an LED. Measure the voltage of a battery. Check if the wire is conducting electricity or not. Parts of a Multimeter A basic Multimeter consists of four parts. They are: Display Selection Knob

Did you know?
WebHere is the value I get: - voltage reading across the battery terminal, Va=3.99V. - voltage reading across the load resistor, Vb=3.796V. - load resistance, R=4.7ohm. Since Vb = Va * [ R / (R+r) ], r = internal resistance. Then, internal resistance of the battery can be determined to be around 240mOhm. Hence, my battery can theoretically ...
