Question

A transformer is designed to change 109 VV into 13,500 VV, and there are 120 turns in the primary coil. Part A How many turns are in the secondary coil

Answer 1

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

$\frac{Vp}{Vs}$ = $\frac{Np}{Ns}$

109/13500 = 120 / Ns

Ns = 14862 turns
