The primary of a transformer when connected to a dc battery of 10 volt 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
Options
(a) 20 V and 0.5 mA
(b) 20 V and 2.0 mA
(c) 10 V and 0.5 mA
(d) zero and therefore no current
Correct Answer:
zero and therefore no current
Explanation:
A transformer is essentially an AC device. DC sources so no mutual induction between coils E₂ = 0 and I₂ = 0
