How much resistance should a capacitor have

WebDec 13, 2024 · The better way to test is to use the resistance ranges of your multi-meter and check for very low resistance, say less than 1 across the capacitor. If your multi-meter has a null or zero function use this to zero out the lead resistance to get a more accurate indication of very low resistances. Web943μF is the capacitance the meter has measured of the capacitor. 943 micro Farads. ESR=2.2Ω is the measured Equivalent Series Resistance (ESR) of the device under test. Well, you may ask, Why is any of this so bad? To begin with it is a 2,200μF capacitor so 943μF is not even close to its marked capacity. But that is not the worst of it.
