Question

The voltage across the primary winding is 350,000 V, and the voltage across the secondary winding is 17,500 V. If the secondary winding has 600 coils, how many coils are in the primary winding?

Answer 1

12000 coils is in the first winding

Answer 2

Answer:

12000 coils

Explanation:

It is given that,

The voltage across the primary winding V₁ = 350,000 V

The voltage across the secondary winding V₂ = 17500 V

Number of coils in secondary winding, N₂ = 600

We have to find the number of coils in primary winding. It can be calculated suing turn ratio equation as :

$\dfrac{V_1}{V_2}=\dfrac{N_1}{N_2}$

$N_1=(\dfrac{V_1}{V_2})\times N_2$

$N_1=(\dfrac{350000}{17500})\times 600$

$N_1=12000$

Hence, the number of coils in primary winding is 12,000
