is it possible to have the terminal potential of a chem cell = its emf when it is in use? why?

Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

in practical purposes, its not possible because of the internal resistance of cell their, is a potential drop between the plates,
however in idealised conditions where we assume internal resistance = 0 ,
we take emf=potential diff even when its in use
