Actually, measuring winding resistance with a multimeter is an iffy situation at best. This is because the multimeter will not tell you if one of the turns is shorted, causing Q to drastically suffer, it will really only tell you if the winding is open, or if it is shorted to something it should not be shorted to, such as the frame.
This is especially true for larger windings, in larger Transformers and motors, because their DC resistance is so close to zero that you might not be able to tell if they are shorted or normal.
Using a multimeter is a good start, to make sure that basics are covered, and it might tell you if the winding is dead shorted, but you need to know for sure what the expected DC resistance is, and you need to know that you multimeter is very good in the low Ohms scale.
Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,
an ohm meter OR multimeter is used to measure the electrical resistance...
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
Multi meterAnswerInstruments that measure current are called ammeters, and instruments that measure voltage are called voltmeters. An instrument that measures resistance is called an ohmmeter. Each of these functions can be combined into one instrument, called a multimeter.
The resistance of a motor winding is expressed in
To measure the resistance of a wire with a multimeter, first turn on the multimeter and set it to the resistance measurement mode. Then, connect the probes of the multimeter to each end of the wire. The multimeter will display the resistance value in ohms.
A multimeter can be used to measure the resistance of a circuit component by setting it to the resistance measurement mode, connecting the probes to the component, and reading the resistance value displayed on the multimeter screen.
You can measure an unknown resistance by using a multimeter set to the resistance measurement function. Connect the unknown resistance in series with the multimeter and apply a known voltage across them. The multimeter will display the resistance value based on the voltage and current readings.
Most multimeter are able to measure resistance.
A multimeter is typically used to measure resistance. It has a setting specifically for measuring resistance and uses probes to make contact with the component being measured. The resistance is then displayed on the multimeter screen.
A voltmeter is a device used to measure voltage, while a multimeter is a versatile device that can measure voltage, current, and resistance, among other electrical properties. Essentially, a voltmeter is a specific function within a multimeter.

To find out which wire has the greatest resistance, you will need to measure the resistance of each wire using a multimeter. Connect the multimeter to each wire separately and record the resistance values displayed. The wire with the highest resistance value will have the greatest resistance.
The resistance of the secondary of a transformer depends on the wire gauge and length of wire used in the winding. Typically, the resistance of the secondary winding of a 24 volt transformer can range from a few ohms to tens of ohms. It is best to measure the resistance using a multimeter for an accurate value.
Resistance of stator winding is the resistance of the copper conductors being used for building the windings of three separate phases, i.e. R-Y-B. These windings are marked like U1-U2, V1-V2 & W1-W2 at the motor terminals (6 nos.) for the three phases, i.e. R-Y-B respectively. We have simply to measure the resistance of each winding by using a multimeter by connecting the terminals (2 no.) to U1 & U2 and so on. The resistance should be in ohms not milliamps [amps is form of measuring current not resistance] milliamps to microamps in case of large motors, it may be in amps in case of small sized motors. But resistance of each winding should be nearly same to each other. This shows the electrical balance among windings & also proves the healthiness of the winding.
To measure the resistance of a component, you can use a multimeter set to the resistance (ohms) setting. Simply connect the two leads of the multimeter to the ends of the component, ensuring that there is no power running through the component. The multimeter will then display the resistance value of the component.
