Electric Current Chapter 19-1: Pages Physics

Electric Current I. Current and charge movement - Current ( I ) – the rate at which electric charge moves through a given area

Electric Current I = ΔQ← (charges passing through a Δt given area) ∟(time interval) - SI unit for current is the ampere (A) 1 A = 1 C/s

Electric Current - Conventional current  The moving charges can be positive, negative, or both  In most conductors (metals) the current is due to movement of negatively charged particles (electrons) because they are freely flowing due to overlapping valence levels, and are more easily removed from an atom due to being held less tightly (less energy required to remove them).

Electric Current

- When a potential difference is applied (difference between negative and positive terminals) to a conductor, an electric field is setup inside the conductor. The force due to that field sets the electrons in motion. Thereby creating a current.
