Re: Should an electrolytic capacitor have measurable resistance?
What you have to remember about multimeters is, an analogue one measures resistance by applying a constant voltage and measuring the current through the unknown resistance (which is why they have a reciprocal-law scale, since R = E / I); whereas a digital one applies a constant current through the unknown resistance and measures the voltage across it.
With an analogue meter, the current flows into the red lead and out of the black; but it means the black lead is at a positive potential WRT the red one.
