    13:00 why is there a sudden increase to Vh, we learnt that theres a gradual increase in polarity as electrons accumulate across the sides and eventually a Vh...

      The gradual increase happens really fast (since electrons move really fast) so it appears instantaneous. Think of how when a ball hits the ground and rebounds, the velocity appears to change instantly on a velocity-time graph (vertical line) even though in reality the acceleration takes some very small amount of time, we consider it as instantaneous. Same here.

      that helped a lot, thank you gang

    when you drew the graph for VH against t, why is VH constant? since from teh equation, VH is propertional to 1/t.
