It is very easy to read resistance with an analog multimeter or ohmmeter. You can read the resistance of variable resisistors (also known as potentiometers or POTS) and standard resistors. A variable resistor can be tuned from zero Ohms all the way up to its maximum rated resistance. For ...

评析:with a needle over a scale应该翻译成“根据指针在刻度上的位置”。You can use a multimeter to test motors, switches, controllers, and many other electrical gadgets. Specific instructions will come with the multimeter (also called a volt-ohmmeter or VOM) you purchase.你可以用万用表来测量...
What is the resistance of an ideal ammeter? A galvanometer can be calibrated to read electric ___. (a) Current (b) Voltage (c) Either of these (d) Neither of these. A galvanometer has a coil with a resistance of 89 ohms. A current of 176 mA causes full-scale deflection. ...
Measure the input and output resistance across input and output terminals of the load cell with an ohmmeter. Compare the resistance values with those in the product data sheet. Compare the resistance from the negative output lead to the negative input lead with the resistance from the negative ou...
s generator, which can be hand-cranked, battery or line-operated, develops a high dc voltage that causes several small currents through and over surfaces of the insulation being tested. The total current is measured by the ohmmeter, which hasan analog indicating scale, digital readout or both....
This is the scenario we must create. In order to do so though, we're going to have to measure the impedance of the galvanometer. An ohmmeter does a good job of that, and in this case the coil's impedance was 5 kiliohms. See [image 3] for the maths!
A test known as ringing, which uses an ohmmeter, can be performed to test the cables if the cable numbers printed on the insulation are not clear. Because the run from the substation yard to the control room is generally a long distance apart, one can place a ground lead on the one ...
Use an ohmmeter to read resistance value between thermister # and thermistor common. See Figure 30, page 50, for sensor plug details. Table 7 Sensor resistance values Sensor resistance values Temp (°F) Sensor ohms Min Max 32 34265 37871 40 27834 30764 50 21630 23907 60 16944 18727 70...
