Answer:

Electric current is defined as the rate at which charge flows through a surface (the cross section of a wire, for example). Despite referring to many different things, the word current is often used by itself instead of the longer, more formal "electric current". The adjective "electric" is implied by the context of the situation being described. The phrase "current through a toaster" surely refers to the flow of electrons through the heating element and not the flow of slices of bread through the slots.

As with all quantities defined as a rate, there are two ways to write the definition of electric current — average current for those who claim ignorance of calculus…

I = ∆q

∆t

and instantaneous current for those with no fear of calculus…

I =

lim

∆t→0

∆q = dq

∆t dt
