How much resistance should a capacitor have
WebWhen capacitors are connected one after another, they are said to be in series. For capacitors in series, the total capacitance can be found by adding the reciprocals of the individual capacitances, and taking the reciprocal of the sum. Therefore, the total capacitance will be lower than the capacitance of any single capacitor in the circuit. . 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.
