# Is the source in parallel or series with the resistor?

• amg63
In summary, the problem involves constructing a circuit model for a generic device using terminal current and voltage measurements. The device is found to contain a resistor and a current source, based on the values from the table. The solution manual determined that the resistor is in parallel with the current source, but the method used is not clear. Additional resources such as the textbook and online sources have not provided a clear answer.

Thank you for your time and effort. It is much appreciated.
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.

Hint: If the solution was a current source value X amps in series with a resistor what would the current be at various voltages?

## 1. What is the difference between a parallel and series circuit?

In a parallel circuit, the components are connected in branches, allowing the current to divide and flow through each component independently. In a series circuit, the components are connected in a single path, allowing the current to flow through each component in succession.

## 2. How do I determine if a source is in parallel or series with a resistor?

To determine if a source is in parallel or series with a resistor, you can visually inspect the circuit. If the source and resistor are connected in the same branch, they are in parallel. If the source and resistor are connected in a single path, they are in series.

## 3. Can a circuit have both parallel and series components?

Yes, a circuit can have both parallel and series components. This is known as a combination circuit. In a combination circuit, there are multiple branches with parallel components, but the branches are connected in series with each other.

## 4. How does the current flow in a parallel circuit?

In a parallel circuit, the current will flow through each branch independently. The total current entering the parallel circuit will be divided among the branches based on the resistance of each branch. This allows the components to have different currents flowing through them.

## 5. How does the current flow in a series circuit?

In a series circuit, the current will flow through each component in succession. This means that the current will be the same at any point in the circuit. The total current entering the series circuit will be the same as the current exiting the circuit.
