A: A VOM can measure the voltage across the load. To test the current if the current surpasses the VOM range just add a very small resistor in series with the load and use ohms law to find the current since you have the voltage drop.
I think it's a test for a shorted armature.
the method can not be used in the case of a d.c series motor

how do test a variable resistor
its easier to undo the motor and test that if that isn't working then it will more than likely be the resistor
To test the blower motor resistor, unplug the resistor connector. Each blower motor switch input terminal on the resistor must have continuity to the resistor output terminal, which is connected to the circuit going to the blower motor. If the blower motor resistor continuity does not check OK, replace the faulty resistor.You need a multimeter to test the resistor block and there should be continuity between all terminals.
Multiple choice tests are often considered the least authentic mode of assessment as they generally do not require deep critical thinking or creativity. They tend to focus on rote memorization and do not effectively assess a student's understanding or application of knowledge.
ohm the resister with a multimeter
spin the motor, if its raspy or rough, any play in it, replace it! i should have done that first! i went through 2 resistors. im bummed!
If you are missing the lower speeds but still have high speed, the resistor is bad.
A pencil and paper.
Remove and test with an ohmmeter Explain how to test with an ohmmeter?
A pencil and 2 pieces of paper.
The 'lead' or graphite in a pencil is softer. Try writing on paper, the pencil will write, the real lead will not
First you need to know the value of the resistor. Follow the link for a handy resistor calculator After determining the value of your resistor simply test the resistor with an ohmmeter to see if it is at true value. General use should be within + or - 5%
