Respuesta :
A transformer is designed to change 109 VV into 13,500 VV, and there are 120 turns in the primary coil. The secondary coil will have 14862 turns
A step-up transformer is a transformer that increases the voltage from the primary coil to the secondary coil while managing the same power at the rated frequency in both coils. It converts low voltage & high current from the primary side to the high voltage & low current on the secondary side of the transformer.
Ns = number of turns on the secondary coil = ?
Np = number of turns on the primary coil = 120
Vs = voltage across the secondary coil = 13500
Vp = voltage across the primary coil = 109
[tex]\frac{Vp}{Vs}[/tex] = [tex]\frac{Np}{Ns}[/tex]
109/13500 = 120 / Ns
Ns = 14862 turns
