WebJan 25, 2024 · how do ohmmeters work, We cannot find out the resistance using ohmmeter in a working or test circuit.To check the resistance, we need to disconnect the power and measure the resistance. The construction of the ohmmeter circuit is a mix of milliammeter (microammeter) with a set of resistances in series and a constant battery source.
WebHow this ohmmeter circuit works is that the 2 resistors in series form a voltage divider circuit. One end of the resistor pair is hooked up to 5V and the other end is hooked up to ground. The 5 volts that the Arduino provides gets divided up between the 2 resistors, depending on the value of the 2 resistors.
