The primary of an ideal transformer has 100 turns and its secondary has 200 turns. Neglecting frictional losses, if the power input to the primary is 100 W, we can expect the power output of the secondary to be

a) 200 W

B) 50W

c)100W

d) none of these

    If losses can be neglected, then power conservation between primary and secondary coils shall apply, of course at different parameters in such a way  V1*I1 = V2*I2; this leads to :

    P2 = P1 = 100 watt
