What does E(max) represent?

Explanation:
E(max) represents the peak voltage—the highest instantaneous value the waveform reaches. This is the amplitude of the voltage swing. It differs from the RMS value, which is the effective heating value and for a sine wave equals E(max) divided by √2. It also differs from the minimum (the negative peak) value, which for a symmetric waveform is −E(max). For a pure AC sine, the average value over a full cycle is zero, so E(max) is not the average voltage.
