Consider this traffic circle.

This is the traffic volume, in units of cars per five minutes

We can set up equations to model how the traffic flows.
(a) Adapt Kirchhoff's Current Law to this circumstance. Is it a reasonable modeling assumption?
(b) Label the three between-road arcs in the circle with a variable. Using the (adapted) Current Law, for each of the three in-out intersections state an equation describing the traffic flow at that node.
(c) Solve that system.
(d) Interpret your solution.
(e) Restate the Voltage Law for this circumstance. How reasonable is it?
