Part 9/11:
Heaviside's exploration led him to discover what he termed the extra current—an oscillating surge of current that could travel along transmission lines, bouncing back and forth in a wave-like manner. Heaviside’s fascination with this transient response demonstrated an advanced understanding of signal behavior far ahead of his time. He considered the effects of grounding and discharging in transmission lines and modeled the complexities of how signals react across varying conditions.
