High ohm reading
WebIf resistance is unknown, the formula can be converted to R = E/I (ohms = volts divided by amps). In the first example, total normal circuit resistance, a known reference value, is 60 … WebOct 25, 2024 · Use a multimeter or an ohmmeter to test the voltage of the electric motor. If there is no resistance or the resistance is uneven, the motor is likely faulty. Check the bearings to make sure they can spin freely. If they can’t, lubricate them. Look on the outside of the motor for other potential problems, like holes or smoke points.

WebFluke 8508A shows a constant very high Ohm reading (around 1 GΩ) Hi! I work in a calibration lab and am working with the 8508A (measure) and the 5522A (source). I accidently performed the ohm zero function on the 5522 with leads going into the high low Input side of the 8505a and now I can't read ohms at all. Pretty sure I have some ... WebSo, spark plug wire resistance is measured in ohms per foot. A high resistance wire can measure around 5,000 ohms per foot, while a low resistance wire can easily fall in the 2-digit ohm per foot range. Here are some generic examples of plug wire resistance per foot: Copper core wire: 1-6,500 ohms. Inductive wire: 650-2,500 ohms.
