Assertion : A step-up transformer changes a low voltage into a high voltage.
Reason : This violate the law of conservation of energy.

A transformer changes the voltage

A transformer changes the voltage

A step up transformer converts a low input voltage into a high output voltage. Does it violate law of conservation of energy? Explain.

A step up transformer converts a low input voltage into a high output voltage. Does it violet law of conservation of energy Explain?

(a) Derive the relationship between the peak and the rms value of current in an a.c. circuit. (b) Describe briefly, with the help of a labelled diagram, working of a step-up transformer. A step-up transformer converts a low voltage into high voltage. Does it not violate the principal of conservation of energy? Explain.
