The formula for energy density is u = U / V (the V here stands for volume, not voltage. Start with the formula from Part F: U = (ε0AdE^2) / 2 The Ad term is equivalent to the volume of a symmetrical box (A is the area of a base, d is the distance between the bases). So divide U by the volume (Ad): U = ((ε0AdE^2) / 2) // (Ad) Simplify to get the final answer: u = (ε0E^2) / 2.

The ground pin on the microcontroller is two things: (1) a voltage reference, and (2) a current return. Voltage Reference: Voltages don''t really exist at single points, voltages are differences between points. This means that to speak sensibly about some single point in a circuit being at a given voltage, it has to be relative to some other point in the circuit.
