Half Peak Potential (E_p/2)

The half peak potential is the potential where the (baseline corrected) current is half of the value of the peak current (i_p). For instance, if a wave has a peak current of 4.6 µA, the E_p/2 of the wave is the potential at which the current is 2.3 µA. There are some fancy analyses that use the E_p/2, but they are beyond the scope of this text.
