Coulomb (SI Unit of Electric Charge)

Introduction : The coulomb is the standard SI unit for electric charge, representing the charge transported by a constant current of one ampere in one second. It's fundamental in electromagnetism, electronics, and electrical engineering.

History & Origin : Named after French physicist Charles-Augustin de Coulomb (1736–1806), who formulated Coulomb's Law. Adopted as the SI unit in 1946, replacing earlier electrostatic and electromagnetic units.

Current Use : Used to quantify battery capacity, capacitor ratings, and electrostatic charges. Essential in circuit design, electrochemistry, and particle physics (e.g., electron charge = ~1.602×10⁻¹⁹ C).

Ampere-Second (Equivalent to Coulomb)

Introduction : Identical to the coulomb, this unit explicitly links charge to current over time (1 A·s = 1 C). It emphasizes the SI definition of charge.

History & Origin : Formalized with the 1946 SI definition of the ampere, reinforcing charge as current × time.

Current Use : Used in physics education to demonstrate charge fundamentals and in precision instruments where time-integrated current matters.
