1. Homework Statement

I have attached the problem with the solution to this thread. Basically, the problem asks to construct the circuit model for a generic device by using the data of terminal current and voltage measurements. From the table that lists the values of voltage and current, we can conclude that the device contains the resistor (rise over run) and the current source (there is some current when no voltage is applied to the device).

## Homework Equations

Ohms and kirchoffs.

## The Attempt at a Solution

I understand how they got 20 amp source and 10 kilo ohm resistor. My biggest question is how can I know in these type of problems, when the source is in parallel or in series with the resistor. What information did the solution manual use when it determined that resistor is in parallel. The manual, the Chegg, the textbook, and youtube with google don't seem to have answers.
