Linear Light Capacitor

basic

As you said, one way to describe a capacitor is V = Q / C. This says that the voltage on a capacitor is proportional to the charge it is holding, and that proportionality constant is the inverse of the capacitance. In the parlance of a linear equation as above, V = f(Q). Since f(Q) = Q/C, it should be clear that this equation is linear because:
