Infinite ESR is the worst possible thing, think about it! OTOH, zero
ESR is what we really want to measure but practically speaking
anything less than 0.5 ohms is okay. Greater than this may be okay up
to about 1 ohm depending on the cap size. The ESR meter will have
charts for this.
A*s*i*m*o*v
... The current limits placed are based on resistance
