In textbook by Serway (1996) the author draws two-dimensional qualitative "graphs"
showing how voltage changes around a circuit (V is on the y-axis and S, the distance along the circuit, is on the x-axis). This paper proposes a natural extension of this idea, and is, in my opinion, more useful than the two-dimensional graphs. In the Serway textbook, the 2-D graph is used to illuminate Kirchhoff’s loop rule; however, these models illustrated Kirchhoff’s loop rule more visually. Moreover, these models also illustrate potential energy changes along the circuit (in analogy with gravity as in the motion of a ball along a closed
loop), and thus emphasize the connection between electric potential and electric potential
energy. This makes the proposed 3-D mechanical models conceptually even richer.
