Select the statement that would earn credit in an AQA GCSE Physics answer. Context: bench-top compass mapping application. Learning objective: (Physics only) (HT only) State that if transformers were 100 percent efficient, the electrical power output would equal the electrical power input.. Which answer is most accurate for Transformers (HT only)? Distinct revision anchor: fluxcue773a coilcue773b fieldcue773c polecue773d gridcue773e motorcue773f generatorcue773g transformercue773h compasscue773i currentcue773j voltagecue773k forcecue773l.
- A.Transformers (HT only): bench-top compass mapping application shows (Physics only) (HT only) State that if transformers were 100 percent efficient, the electrical power output would equal the electrical power input. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It treats a permanent magnet as if it only works when current flows. (boundary error).
- C.It confuses the magnetic field with an electric field. (application error).
- D.It describes energy transfer but misses the force or field interaction. (measurement error).
