C.40,000,000v

D.3725v

Answer:

Voltage in primary coil is 3.91 V

Explanation:

For transformer we know that the working principle is given as

[tex]\frac{V_1}{V_2} = \frac{N_1}{N_2}[/tex]

here we know that

[tex]V_1 [tex] = voltage in primary coil

[tex]V_2 = 25 V[/tex]

[tex]N_1 = 500[/tex]

[tex]N_2 = 3200[/tex]

Now we have

[tex]\frac{V_1}{25} = \frac{500}{3200}[/tex]

[tex]V_1 = 3.91 V[/tex]
