** URGENT** 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?

A- 30 coils

B- 583 coils

C- 12,000 coils

D- 332,500 coils

Respuesta :

As we know that in transformers we have

[tex]\frac{V_s}{V_p} = \frac{N_s}{N_p}[/tex]

here we know that

[tex]V_s = 17,500 Volts[/tex]

[tex]V_p = 350,000 Volts[/tex]

[tex]N_s = 600 coils[/tex]

now from above equation we will have

[tex]\frac{17500}{350000} = \frac{600}{N_p}[/tex]

[tex]N_p = 600\times \frac{350000}{17500}[/tex]

[tex]N_p = 12000 coils[/tex]

Answer:

12,000 coils

Explanation:

edge
