Why adding resistors can actually make current flow faster

You've probably been taught that electrical resistance is just a roadblock for current. To see why that isn't always true, let's picture a simple water pipe. The intense pressure pushing the water forward is your voltage.

But if that pipe suddenly narrows, the pinch restricts how much water can get through. That pinch is resistance. In 1827, Georg Ohm realized the resulting flow—the current—is simply the push divided by the pinch.

Since resistance blocks flow, it seems totally obvious that adding more resistors would just choke the current further. But here is the strange part: adding resistors can sometimes make the current flow faster.
