Circuit lets you test capacitors

Electrolytic capacitors tend to leak with time. The circuit in Figure 1 lets you test capacitors and decide whether they’re worth using. You can set the constraint on the leakiness through the values of CREF/RREF. The values in the figure are typical for general testing of all capacitors, from 1-nF ceramic versions to 1000-ΞΌF electrolytic
