Outdoors w/ a solar load
What is Boyles Law?
States that when pressure exerted by a gas is reduced, the volume increases
At a constant TEMPERATURE, a fixed mass of gas occupies a volume that is inversely proportional to the pressure exerted on it.

Case-control study
Reflection of correlation between two sets of numbers
Spearman rank (or rho)
Defined as the amount of electrical force that drives the current between two points
Voltage
Defined as the measure of opposition to the flow of steady electrical current
