Historically, a farad was regarded as an inconveniently large unit, both electrically and physically.
This design gave a capacitor with a capacitance value in the one farad area, significantly higher than electrolytic capacitors of the same dimensions.
This group also recognized that any one of the practical units already in use (ohm, ampere, volt, henry, farad, coulomb, and weber), could equally serve as the fourth fundamental unit.
