Planck charge

The Planck charge is a fundamental unit of electric charge derived from natural constants in physics, specifically the speed of light, gravitational constant, and Planck's constant. It represents a theoretical "building block" for charge, providing a scale to understand electromagnetic phenomena at the most fundamental level. The value of the Planck charge (~1.88 x 10^-18 coulombs) is much smaller than the charge of an electron. It helps physicists explore concepts in quantum mechanics and unified theories, offering a way to describe forces and particles without reference to human-made measurement units.
