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:

Component 1

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:

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:

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:
