Document Summary

Abstractions reduce complexity by combining multiple primitives into a single entity. The voltage divided on the left acts as a module that produces 8v, regardless of loading of bulb on the right. Changing an element changes voltages and currents systematically. Consider the changes in v and i when r is changed. The equations for the three leftmost elements are linear. The current-voltage relation summarizes all possible behaviors of circuit regardless of what the circuit is connected to. We can think about an entire circuit as a single element: a one-port. If a circuit connects to the world via two terminals, then that circuit can be represented by a single generalized element called a one-port. This is regardless of how many components are in the circuit. This is analogous to replacing delays, gains, and adders with a system function combining a sequence of operations in a procedure call combining diverse data in a list.
