(i) With the help of a labelled diagram, describe briefly the underlying principle and working of a step up transformer. (ii) A step up transformer converts a low input voltage into a high output voltage. Does it violate law of conservation of energy? Explain. (iii) Write any two sources of energy loss in a transformer. |

Answer» Solution :(i) N/A (ii) A step up TRANSFORMER does not violate the LAW of conservation of energy. ALTHOUGH it enhances the output voltage but correspondingly reduces, the circuit current so that POWER output of even an ideal transformer is same as the power input. (iii) N/A |
