Music for this Problem

For each of the circuits and current-voltage characteristics shown below, specify the component, if any, that could be added in the box to cause the current I and the voltage V to have the pictured relationship. Valid components are limited to:

  • resistors with finite positive resistance,
  • voltage sources with finite nonzero voltage,
  • and current sources with finite nonzero current.

Specify the appropriate component by naming its type and its value (be careful of directionality!). Examples:

 

Single Component

What single component, if any, can be drawn in the box in the circuit on the left to cause the current I and the voltage V to be related as shown in the graph on the right?

Component Type or None:
Component Value or None:
 

Single Component 2

What single component, if any, can be drawn in the box in the circuit on the left to cause the current I and the voltage V to be related as shown in the graph on the right?

Component Type or None:
Component Value or None:
 

Single Component 3

What single component, if any, can be drawn in the box in the circuit on the left to cause the current I and the voltage V to be related as shown in the graph on the right?

Component Type or None:
Component Value or None:
 

Series

What single component, if any, can be drawn in the box in the circuit on the left to cause the current I and the voltage V to be related as shown in the graph on the right?

Component Type or None:
Component Value or None:
 

Series 2

What single component, if any, can be drawn in the box in the circuit on the left to cause the current I and the voltage V to be related as shown in the graph on the right?

Component Type or None:
Component Value or None:
 

Parallel

What single component, if any, can be drawn in the box in the circuit on the left to cause the current I and the voltage V to be related as shown in the graph on the right?

Component Type or None:
Component Value or None:
 

Parallel 2

What single component, if any, can be drawn in the box in the circuit on the left to cause the current I and the voltage V to be related as shown in the graph on the right?

Component Type or None:
Component Value or None:

More Complicated

What single component, if any, can be drawn in the box in the circuit on the left to cause the current I and the voltage V to be related as shown in the graph on the right?

Optional Hint
Show/Hide If you pick a value of $I$, you know the associated value of $V$ (from the curve!). Using this, you should be able to solve for the current through, and the voltage across, the unknown component when $I$ and $V$ have those values. This gives you one point on that mystery component's $IV$ curve.

Finding one more point on the IV curve should tell you what type of component is missing, as well as its parameter.

Component Type or None:
Component Value or None:
