Question

The primary of a transformer when connected to a dc battery of $10V$ draws a current of $1mA$. 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. $20V$ and $2.0mA$
• B. $10V$ and $0.5mA$
• C. Zero volt and therefore no current
• D. $20V$ and $0.5mA$

Answer 1

The correct option is C Zero volt and therefore no current

Transformer doesn't work on DC supply.
