Question

A transformer is designed to change 106 v into 13,500 v, and there are 128 turns in the primary coil. How many turns are in the secondary coil?

Answer 1

The number of turns in the secondary coil is 16301.

Calculation:

A transformer is a device that changes voltage levels from low to high and vice versa; the conversion is based on the ratio of the turns in the primary and secondary coils.

The relation between voltage and the number of turns in coils is given as,

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

where,

Vp = voltage of the primary coil

Vs = voltage of the secondary coil

Np = number of turns in the primary coil

Ns = number of turns in the secondary coil

Given,

Vp = 106 V

Vs = 13,500 V

Np = 128

To find,

Ns =?

Put the values in the formula,

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

$\frac{106}{13,500} =\frac{128}{Ns}$

Ns = 16301

Therefore, the number of turns in the secondary coil is 16301.
