# Wrapping It Up

So there are many ways to look at a simple formula like Ohm's law. Even though there are only three quantities involved, there are six different graphs that can be plotted:

- Current as a function of voltage
- Current as a function of resistance
- Voltage as a function of current
- Voltage as a function of resistance
- Resistance as a function of voltage
- Resistance as a function of current
