1. How does the relationship between force and mass in Newton's second law compare to the relationship of current and voltage in Ohm's law (holding the other values constant)?
2.
How does the relationship between mass and acceleration compare to the relationship between current and resistance (when the other values are constant)?
3. What type of plot would you expect to see if you graphed voltage versus current?

What is a fundamental relationship between the voltage across a resistor, the current flowing through a resistor, and the resistance of the resistor?

# data[].attributes.body
Georg Simon Ohm observed that as the voltage across a resistor changes, so does the current. For a constant resistance, if the voltage increases, the current increases proportionally. If the voltage decreases, the current decreases proportionally. Conversely, for a constant voltage, if the resistance increases, the current decreases and vice versa. In other words, current is directly proportional to voltage and inversely proportional to resistance. This is expressed in Ohm's law as:
