BACKGROUND / MOTIVATION:
Many important observations in math and science can be described by short, but powerful, equations:
* The Pythagorean Theorem (c^2 = a^2 + b^2) * Newton's Second Law of Motion (F = ma) * Einstein's Mass-Energy Equivalence (E = mc^2)
For electrical circuits, one of the most useful and important equations is:
* Ohm's Law (V = IR)
Ohm's Law describes the relationship between voltage (V), current (I), and resistance (R) in electrical circuits.

Given the current (I) through a resistor with resistance (R), create a function that will return the voltage (V) across the resistor.
