What is the basic unit of electrical quantity?

The basic unit of electrical quantity is the Coulomb. It is defined as the amount of electric charge that is transported by a constant current of one ampere in one second. In the context of electrical engineering and physics, understanding charge is fundamental because it relates directly to how electricity is stored and transmitted in circuits.

The Coulomb is a vital part of the International System of Units (SI) and is used to quantify the amount of electric charge that can influence electric fields and currents in various applications, from simple circuits to complex electronic systems. Recognizing Coulombs as a unit allows technicians to work effectively with electrical components and systems, since managing and calculating charge is essential in ensuring proper function and safety in electronic devices.
