Answer:

[tex]\frac{N_2}{N_1}= 2[/tex]

Explanation:

From the question we are told that:

Power [tex]W=960W[/tex]

Voltage [tex]V=240v[/tex]

USA-standard [tex]V_{usa}=120 V[/tex]

Applying A step down transformer

Generally the equation for a Transformer is mathematically given by

 [tex]\frac{v_2}{v_1}c=\frac{N_2}{N_1}[/tex]

 [tex]\frac{N_2}{N_1}=\frac{240}{120}[/tex]

 [tex]\frac{N_2}{N_1}= 2[/tex]

Therefore

She can use a turns ratio of 2
