Circuit lets you test capacitors for leakage

Circuit lets you test capacitors for leakage

Raju R Baddi @ has published a circuit that enable you to test electrolytic capacitors and decide if worth using it on a circuit.

The values in the figure are typical for general testing of all capacitors, from 1-nF ceramic versions to 1000-μF electrolytic types. The value of CREF in the circuit is near the value of the test capacitor, CX. You can also choose RREF, by a rotary-switching arrangement, to be greater than or less than 22 MΩ.
