Q. The turn ratio of a transformer is 1:2. An electrolytic DC cell of emf 2 V is connected to its primary. The output voltage across transformer is
A) Zero
B) 4 V
C) 2.4 V
D) 12 V
Explanation
(d) As transformers works only on AC, so when electrolytic DC cell of emf 2 V is connected to primary of transformer then there is no output across its output.
