- The coulomb unit is derived from SI unit ampere for electric current i.
- Current is the rate Δq/Δt at which charge moves past a point or through a region
- in which i is the current (in amperes) and dq (in coulombs) is the amount of charge moving
- past a point or through a region in time dt (in seconds).
- Therefore,
