Answer:
Number of coil in the output is 39938
Explanation:
We have given a step up transformer
Input voltage of transformer, that is primary voltage [tex]v_p=20000volt[/tex]
Output voltage, that is secondary voltage [tex]v_s=355000volt[/tex]
Number of turns in primary [tex]N_p=2250[/tex]
For transformer we know that [tex]\frac{V_p}{V_s}=\frac{N_p}{N_s}[/tex]
[tex]\frac{20000}{355000}=\frac{2250}{N_s}[/tex]
[tex]N_s=39937.5[/tex]
As the number of turns can not be in fraction so number of turns in the output coil is 39938
