8.5.P17

In discussing electric current flow, we specified three principles known as Kirchhoff's laws that help us calculate what current flows there will be in any circuit. Furthermore, we developed a number of analogies to help us think about electric current. Pick one of Kirchhoff's laws and one of the anologies. State the law clearly and describe how an analogy helps you think about it. If none of our analogies help you think about Kirchhoff's laws, or if they confuse you when thinking about the laws, explain why and give a particular example.
