Coulombova

Coulombova refers to a unit of electric charge, named after the French physicist Charles-Augustin de Coulomb. It is the standard unit of charge in the International System of Units (SI). One Coulomb is defined as the amount of electric charge transported by a constant current of one ampere in one second.

The concept of electric charge is fundamental to electromagnetism. It is a property of matter that causes it to experience a force when placed in an electric or magnetic field. Charges are typically quantized, meaning they exist in discrete units, and the elementary charge, the magnitude of the charge of a single proton or electron, is approximately 1.602 x 10^-19 Coulombs.

The relationship between electric charge, current, and time is described by the equation Q = I * t, where Q is the charge in Coulombs, I is the current in Amperes, and t is the time in seconds. This fundamental relationship underscores the definition of the Coulomb. Historically, Coulomb's Law describes the electrostatic force between two point charges, stating that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
