Free electron -- Free electron are the particle which carry a fix amount charge in a electric field or a electric conductor.

 

                                                  Electric current

Electric current  is the nothing but the flow of free electron cross the electric conductor
Each electron has got a fix amount of charge.

"Electric current is the amount of charge flow in unit time across a electric conductor"
