I–V plot
By convention, when plotting an I-V characteristic (current vs. voltage curve):
| Variable | Symbol | Axis | Variable type | Axis name |
|---|---|---|---|---|
| Voltage | V | horizontal (x-axis) | independent variable | abscissa |
| Current | I | vertical (y-axis) | dependent variable | ordinate |
In this orientation the slope of the curve (m) is in Siemens, which is 1/Ohms. When plot as V-I (flipping the axes) the slope is in Ohms.
