If an electrical device has constant power and frequency ( same power and frequency at input and output respectively ) then does it mean that the device is transformer ?
Is there no electrical device other than transformer which have constant power and frequency ( atleast one of them ) ?
If yes, then does it mean that conservation of energy is not maintained ( when I talk in terms of power ) ?
