Question

Circle the answers 6 The results show voltage is stepped [up] (downj trom primary to secondary, and that current is correspondingly stepped lup] (down) 7. For a step-up transformer, there are [more tewer] turns in the secordary coi than in the primary For such a transtormer, there is (more] [ess] curent in the secondary than in the primary 8 A transformer can step up [voltage (energy and power] but in no way can it step up voltage] (energy and power) 9 if 120 V is used to power a toy electric train that operates on 6 V, then a (step up] (step down] transtormer should be used that has a pnmary to seoondary turns ratio of mol Roil 10 A transtormer operates on (dc] (ac] Electnicty and mogne tism connect to become light because the magnetic field within the iron core must Icontinually change) [remain steady 100

Explanation / Answer

6. Voltage step-UP, current step-DOWN
7. More turns, Less current
8. ...can step-up Voltage, but.... cannot step-up Energy/ power
9. Step-DOWN, with turns ratio 20:1
10. Transformer works on AC .... must Continually change.
