As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

Capacitor discharge circuits are used extensively in fast pulse generation. In such applications, the capacitor's stray inductance (or equivalent series inductance ...

A 65-year-old woman presented to her primary care physician with acute visual loss in the left eye. An ophthalmologist noted a cotton wool spot and she subsequently underwent testing, including ...

We read the paper by Levy et al 1 with interest, however, we believe that it contains several weaknesses which should be discussed. As it is well known the diagnosis of GCA is based on the combination ...

A 9-V battery or an optional ac wall adapter can power the Model 881 portable in-circuit equivalent-series resistance (ESR) and dc resistance (DCR) capacitor tester ...
