The relationship between variables might be either directly porportional to each other or inversely proportional to each other. <em>For instance, the current flowing is _</em><em><u>directly</u></em><em>_ </em><em>proportional to the potential difference across</em> it.
---------------------
Since I do not have the graph, I will propose two potential options and I will describe each of them.
I suggest you to choose the one that matches the shape of graph 3.
<h3>Graphs</h3>- Probably your graph is composed of the X and Y axes, perpendicularly placed, in a way in which four quadrants are formed.
- You might see that one of the axes represents the current (I), and the other one represents the potential difference (V).
- And a straight line that represents the relationship between the current and the potential difference.
- The direction of the straight line reflects the relationship between variables.
- The change on each variable is proportional to the change on the other variable. Now we have to analyze how that change occurs.
<em>The current flowing through this component is __</em><u><em>DIRECTLY</em></u><em>__ proportional to the potential difference across it</em>.
If this is the case of your graph, you should see the straight line crossing from the left inferior quadrant to the right superior one.
The direction of the line suggests that one of the variables increases as the other one increases too. <em>The current increases as the potential increases. </em>
<h3> </h3><em>This is the case of the </em><em>Ohm's law.</em><em> </em>
<h3 /><h3 /><h3>Option 2 </h3><em>The current flowing through this component is __</em><u><em>INVERSELY</em></u><u><em>_</em></u><em>_ proportional to the potential difference across it.</em>
If this is the case of your graph, you should see the straight line crossing the right quadrant from the superior left corner to the inferior right one.
The direction of the line suggests that the variable represented in the Y ax decreases as the other one increases.
For instance, The current decreases as the potential increases. Or the potential decreases as the current increases.
In the attached files you will find graphs of both options.
