    Ideally, you should use 18 for the powered plates and 20 for the bipolars.
    yes i agree, thin plates has more resistance just as thin wires has more resistance. to keep your resistance down use thick enough wires and plates. and configure your cell with 6 n plates

    Look carefully at these two entirely different situations.

    Wire gauge resistance is proportional to the cross sectional area and the length of travel.

    Electron travel through a plate follows suit. The larger your plate area, the lower the resistance to electron flow. The shorter the distance to travel (thinner sheet vs thicker) the lower the resistance to current flow.
