Voltage Vs Current Graphs?

Answer

A voltage vs. current graph is a graph that shows the relationship between the voltage and the current of a unit. Their curve or gradient is usually not equal to the resistance. The physical meaning of slope for voltages vs. current graphs is the resistance since it is the result of the two relationships.
Q&A Related to "Voltage Vs Current Graphs?"
According to Ohm's Law, R. = V/I, the physical meaning of slope for voltages vs current graphs is resistance.

In a graph of voltage vs. current, the graph would be a straight line, and the slope of this line would be the device's resistance.

I think you've got it! The slope is defined as the change in y divided by the change in x. In this case, it would be your change in voltage/change in current. Ohm's law gives you

Impedance, similarly to resistance, equals maximum voltage divided by maximum current. The plot will be an ellipse if a constant AC voltage is applied. It's an ellipse because voltage
