Electric current is defined as the amount of charge passing through a point in a circuit per unit time. The symbol for electric current is I, and it is measured in amperes (A). The expression for electric current is I = ΔQ/Δt, where ΔQ is the charge passing through a point in a circuit and Δt is the time taken for that charge to pass through the point. Therefore, choice D, I = ΔQ/Δt, is the correct expression for electric current.
