Why is charge a derived quantity?
Ampere seconds, not amperes per second.AbsoluteZer0 said:Electric charge is measured in Coulombs, or Amperes per second.

Charge is considered a derived quantity because it is not a fundamental physical property like mass or length. Instead, it is defined in terms of other fundamental quantities, such as electric current and voltage, through the equation Q = I * t.
The fundamental quantities that charge is derived from are electric current and voltage. Electric current is the rate at which electric charge flows, and voltage is the measure of electric potential difference between two points.
Charge is measured in units called coulombs (C). One coulomb is equal to the amount of charge transferred by a current of one ampere in one second.
Charge is important in science because it is a fundamental property of matter and is the basis for many physical phenomena, such as electricity, magnetism, and chemical bonding. Understanding charge allows scientists to explain and predict the behavior of particles and systems.
In most cases, charge cannot be created or destroyed. According to the law of conservation of charge, the total amount of charge in a closed system remains constant. However, charge can be transferred from one object to another through various processes, such as charging by friction or conduction.
