You will have to be more specific and provide context.

I'm going to assume your talking about electric current?

In that case, electric current is defined to be the rate of charge passing a particular point.

Charge is given the symbol Q, time t. So if the rate is constant, the current I = Q/t.

In terms of your equation, -e is the charge of one electron, so your current would represent the rate at which a single electron (or something with that amount of charge) passes a particular point.
