ESR tests can be performed when the capacitor is in the circuit or out of the circuit. For capacitors connected in parallel, the measurement gives the overall resistance. The specific capacitors must be removed if their individual ESR is to be determined. However, if there are hundreds of capacitors, it is tedious to remove each capacitor, and there is an increased …
