A) voltage
B) current
C) frequency
D) None of these
Correct Answer: C
Solution :
Transformer is based on the principle of mutual induction is used for converting large alternating current at low voltage into small current at high voltage and vice-versa. By the process of mutual induction an alternating emf of the same frequency is induced in the secondary coil. Hence, the quantity that remains unchanged in a transformer is frequency.
