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 :
[tex]\dfrac{V_1}{V_2}=\dfrac{N_1}{N_2}[/tex]
[tex]N_1=(\dfrac{V_1}{V_2})\times N_2[/tex]
[tex]N_1=(\dfrac{350000}{17500})\times 600[/tex]
[tex]N_1=12000[/tex]
Hence, the number of coils in primary winding is 12,000
