NEET 2013 Physics Transformers MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The primary of a transformer when connected to the battery of 10 Volt draws a current of 1 mA. The number of turns of the primary and secondary windings are 50 and 100 respectively. The voltage in the secondary and the current drawn by the circuit in the secondary are respectively:
A
20 V and 2.0 mA
B
10 V and 0.5 mA
C
Zero volt and therefore no current
D
20 V and 0.5 mA
Correct Answer
Option C
Detailed Explanation
A transformer cannot operate on DC supply. Therefore, the voltage and current in the secondary are zero.
