20. A transformer having 6000 input windings is used to run a saw mill
rated 60 Hz and 720V. If it is connected to an AC source of 220V,
calculated the number of turns in the output coil of the transformer.

Formula : N1/N2 =V1/V2 (Turns Ratio)
Where N is the number of turns in the coil and V is the voltage across the coil.
N1= 6000
N2=?
V1=720/60 =12
V2=220
N2=6000x220/12
N2=110000
Number of coil in the output coil of the transformer
