Define the unit of current.
The unit of electric current is the ampere, denoted by the symbol A. It's named after André-Marie Ampère, a French mathematician and physicist who did pioneering work in electromagnetism.
There are two ways to define an ampere:
- One ampere is the flow of electric charge across a surface at the rate of one coulomb (the SI unit of electric charge) per second.
- In simpler terms, it represents the amount of electrical charge moving past a point in a circuit each second.
The ampere is a fundamental unit in the International System of Units (SI) and is crucial for various applications in electronics, electrical engineering, and physics.
