Answer

80 coils

Explanation

The turn rule of a transformer says that, the amount of voltage induced in the secondary coil is proportional to the number of coil. It is simplified by the ratio:

Np/Ns = Vp/Vs

200/Ns = 25,000/10,000

200 * 10,000 = 25,000Ns

2,000,000 = 25000Ns

Dividing both sides by 25,000,

Ns = 2,000,000/25,000

= 80 coils
