The primary and the secondary coils of a transformer contain 10 and 10

1.	The primary and the secondary coils of a transformer contain 10 and 100 turns, respectively. The primary coil is connected to a battery that supplies a constant voltage of 1.5 V. The voltage across the secondary coil is(a) 1.5 V(b) 0.15 V(c) 0.0 V(d) 15 V
Answer» Answer is : (c) 0.0 V As primary voltage is constant, there is no change of magnetic flux of secondary coil. So, there is no induction and hence voltage across secondary is zero.

Answer»

Answer is : (c) 0.0 V

As primary voltage is constant, there is no change of magnetic flux of secondary coil.

So, there is no induction and hence voltage across secondary is zero.
