For resistance values exceeding 100, a single-arm bridge is utilized, while for values below 102, a double-arm bridge is employed. In the voltage drop method, a power source consisting of a 2-12V battery is used, and the connections of the voltmeter and ammeter are directly attached to the terminals of the winding under test. During the measurement process, it is essential to wait for the current to stabilize before connecting the voltmeter and, prior to cutting off the power supply, disconnect the voltmeter to obtain the measured resistance value (R = UfI)."}
