A step up transformer does not violate the law of conservation of energy. Although it enhancesthe output voltage but correspondingly reduces, the circuit current so that power output of even an ideal transformer is same as the power input.
Class 12 Physics Chapter 7 Alternating current Session 2024-2025.
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 does not violate the law of conservation of energy. It increases voltage but decreases current proportionally, ensuring the input and output power (minus losses) remain equal. The total energy is conserved, as transformers efficiently transfer electrical energy without creating or destroying it.
