Answer:

[tex]4:1[/tex]

Explanation:

[tex]N_p[/tex] = Number of turns of primary coil = 200

[tex]N_s[/tex] = Number of turns of secondary coil = 50

The transformer turn ratio is given by

[tex]\dfrac{N_p}{N_s}=\dfrac{200}{50}[/tex]

[tex]\Rightarrow \dfrac{N_p}{N_s}=\dfrac{4}{1}[/tex]

[tex]\Rightarrow \dfrac{N_p}{N_s}=4:1[/tex]

The transformer turn ratio is [tex]4:1[/tex].
