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

Text Solution

Verified by Experts

No.
A step up transformer steps of the voltage while its steps down the current. So the input and output power remain same (provided there is no loss). Hence there is no violation of the principle of energy conservation.
