The primary winding of transformer when connected to a $d c$ battery of 10 Volt draws a current of $1 \mathrm{~mA}$. 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

  $20 \mathrm{~V}$ and $2.0 \mathrm{~mA}$
• B

  $10 \mathrm{~V}$ and $0.5 \mathrm{~mA}$
• Correct answer
  C

  Zero volt and therefore no current
• D

  $20 \mathrm{~V}$ and $0.5 \mathrm{~mA}$

Hence, the correct answer is option: 'C'.
