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:

Options

A $20 \mathrm{~V}$ and $2.0 \mathrm{~mA}$
B $10 \mathrm{~V}$ and $0.5 \mathrm{~mA}$
CZero volt and therefore no current
D $20 \mathrm{~V}$ and $0.5 \mathrm{~mA}$

Correct answer

C. Zero volt and therefore no current

Step-by-step solution

Transformer can not work on dc.
