In a half-wave dipole, the highest distribution of ________ occurs at the middle.

The electrical characteristics of a resonant half-wave dipole include standing waves that vary predictably along the length of the wire. At the exact center of the antenna, electrons are moving most freely back and forth, meaning the current distribution is at its absolute highest. Conversely, the voltage at the center is at its lowest. Because impedance is calculated as voltage divided by current (Z = E/I), this combination of high current and low voltage results in a low feed-point impedance, making it easy to match with standard coaxial cables. Choosing voltage as the answer is incorrect because voltage peaks at the physical ends of the elements, not the middle.
