34 The diagram shows a simple circuit. S R Which statement is correct? A When switch S is closed, the e.m.f. of the battery falls because work is done against the internal resistance of the battery. B When switch S is closed, the e.m.f. of the battery falls because work is done against the resistance of R. C When switch S is closed, the potential difference across the battery falls because work is done against the internal resistance of the battery. D When switch S is closed, the potential difference across the battery falls because work is done against the resistance of R.
