Electric field lines radiating from a central charged sphere. It's a clean, elegant depiction of one of the most fundamental concepts in electromagnetism: how electric charges exert force on each other across space. The symmetrical, thin lines visually represent the direction and strength of the electric force, moving from positive to negative charges.

This concept is deeply rooted in the work of Benjamin Franklin, one of the most famous polymaths of the 18th century. It was Franklin who, through his ingenious experiments with static electricity, first proposed the convention of "positive" and "negative" charges around 1747. Before him, scientists often spoke of two types of "electric fluid." Franklin's model, involving a single electric fluid with either an excess (positive) or deficit (negative), provided a clearer framework that laid the groundwork for all subsequent studies in electricity. His choice of terminology, still used today, was a monumental step in standardizing the language of physics.
