The power gain, ignoring loss in the transformer, will bePgain = Vgain.Igain= 10 .0 ,1 = 1 A step-down transformer ... transformer in Fig 1- 2 has a voltage ratio of 10 :1. With 12 0V across the primary, 12 V ac is developed across the secondary. If it were not for the diode, there would be 12 V ac across the load...
