Which explanation best links the observation to the physics? Context: National Grid substation application. Learning objective: (Physics only) (HT only) Recall and apply the equation Vp x Ip = Vs x Is for a 100 percent efficient transformer.. Which answer is most accurate for Transformers (HT only)?

- A.Transformers (HT only): National Grid substation application shows (Physics only) (HT only) Recall and apply the equation Vp x Ip = Vs x Is for a 100 percent efficient transformer. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It says field lines travel from south to north outside the magnet. (efficiency error).
- C.It makes AC and DC equivalent. (energy-transfer error).
- D.It ignores relative motion or changing magnetic flux. (field-shape error).
