Spletpred toliko dnevi: 2 · 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 … SpletDC motor field windings are subject to _____ in a winding, an open winding, and individual windings shorted to the motor frame or to other windings. shorts Field windings should have about 1 to 10 ohms of resistance end to end, sometimes slightly higher.
