How do you know that analog multimeter is working or not?

To check if an analog multimeter is functioning properly, first ensure it's set to the correct measurement range. You can test it by measuring a known voltage or resistance; for instance, using a fresh battery or a known resistor value. Observe the needle movement—if it responds accurately and consistently to the test input, the multimeter is likely working. Additionally, you can verify continuity by checking if the needle moves when the probes are shorted together.

Why the resistance of a capacitor is infinite when measures with an ohmmeter?

The typical ohmmeter measures DC resistance by providing DC current and measuring the voltage drop accross the resistor. By definition, the 'ideal' capacitor is an open circuit to DC current and voltage. By definition, an open circuit has infinite resistance. Of course, real-world capacitors are not ideal. They have a very high parallel leakage resistance and a very small series resistance. And, different meters can measure different ranges of resistance. So, you may not get an infinite/overload measurement on some capacitors with some meters. You may get a very high resistance instead. If so, you are not really measuring the resistance of the 'capacitor', but rather that of the imperfections in the component manufactured to be a capacitor. ANSWER: The ohmmeter battery will charge the capacitor in 5 time RC after that it quirts there is no more current flow. Any body that claim to be able to check resistance of a capacitor i just a wannabe


How do you test a dual capacitor?

Depending on the value, it varies. Using a multimeter set for Kilohms resistance, check that it appears open circuit. This may be hard to determine, due to other components in circuit. It should NOT show zero resistance. Electrolytic capacitors above 1 microFarad will show some storage of charge. Using the meter with the probes one way, there should be a percepible rise of resistance. Reverve the leads and you should get an intial negative value followed by a slow rise in resistance. If there is no perceptible rise, it could be open circuit. If it shows Zero, it will indicate a dead short.
