Electric circuits, Current, and resistance (Chapter 22 and 23)

Current Q I t ∆ = ∆ If electric charge (e.g. electron) moves, we will say an electric current, I, is set to exist. An electric current, I, is the rate at which net charge (∆Q) flows through a surface area A Current’s units = C/S and often written as A (Ampere) Although current carriers (i.e., charges) could be “+”or “ … ................
