Rather than trying to create more analogies you would be far better off working through the basic principals again, it will stand you in good stead later. Here is an excellent self paced tutorial on the subject that will not only help clear up any basic misunderstanding but will teach you far more than you expect: http://www.americanradiohistory.com/Archive-Hands-On-Electronics/Hands-On-1= 986-12.pdf Turn to page 73, Resistors and Resistive Circuits, and work through all the examples, you will surprise yourself.
