A)0.5
B)0.707
C)1
D)1.414
E)2

Question

Quizplus · Accepted Answer

The power ratio in a transformer is equal to the square of the turns ratio. In this case, the turns ratio is 2000/1000 = 2. Therefore, the power ratio is 2^2 = 4. The power dissipated in the primary is 4 times the power dissipated in the secondary. So, the ratio of power dissipated in the primary to the secondary is 4/1 = 1.
