Question

The primary of a transformer when connected to a dc 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 0.5 mA [NEET Kar. 2013]
(b) 20 V and 2.0 mA
(c) 10 V and 0.5 mA
(d) Zero and therefore no current
