How to choose a good electrolytic capacitor?

When checking its quality, the resistance of the electrolytic capacitor (6V or l0V) with lower voltage withstand should be placed in R 100 or R 6550 Such electrolytic capacitors are good. The larger the capacity of the electrolytic capacitor, the longer the charging time, the slower the pointer oscillating.
