A 220V/12V single-phase transformer is designed for use in India and rated 100 VA at 50 Hz. Later, this unit is shipped to the USA where it is used as a 110V/6V transformer at 60 Hz.
Which of the following statements is/are correct?
A
No-load current drawn would be smaller for operation in the USA compared to that in India
B
For the same load current, the losses would be higher in the USA compared to that in India
C
The peak magnetic flux density in the core would be higher while operating in the USA compared to that in India
D
The eddy current losses in the core would be approximately 44% higher while operating in the USA compared to that in India

Correct : a,d
