In your reading for this module, you learned how the electric resistance of an object changes with cross-sectional area and with length. let’s compare the flow of current in a circuit to the flow of water being sucked through a straw. for purposes of this comparison, the flow of water is equivalent to current and your suction strength is equivalent to voltage. suppose you have four straws, as follows:
short and fat
short and thin
long and fat
long and thin
in your initial post to the discussion, respond to the following:
which of the four straws described above gives the highest water current? lowest?
next, consider how water would flow through two other configurations of these same four straws:
one version where the four straws are taped end-to-end to make one long straw
the other version where all four straws are taped together side by side, so you would suck water through all four at the same time
which of these two configurations produces the lowest current? which produces the highest? why?
