๐Ÿค” The Confusion of Understanding Voltage

This paragraph follows the journey of a student from age 14 to 19, grappling with the concept of voltage in various science classes. Initially, the student struggles with understanding the textbook definitions of joules and coulombs, leading to confusion about how voltage relates to energy and work. The narrative continues through a physics class where the student learns about electric forces, fields, and potential energy, but still questions the formulas and their meanings. By university, the student encounters voltage dividers and begins to grasp the concept of voltage as a force that drives charge, akin to a ball rolling down a hill.
