The electricity received at an electrical substation has a potential difference of 20,000 V. What should the ratio of the turns
iren2701 [21]

The turn ratio of the transformer is 40.

<h3 />

<h3>What is a transformer?</h3>

A transformer is an electrical device that is used to step up or step down voltage.

The formula for calculating the turns ratio of a transformer is given below.

<h3> Formula</h3>
  • a = V/v.......... Equation 1

Where:

  • V = Primary voltage
  • v = Secondary voltage
  • a = Turns ratio of the transformer

From the question,

Given:

  • V = 20000 V
  • v = 500 v

Substitute the values above into equation 1

  • a = 20000/500
  • a = 40.

Hence, The turn ratio of the transformer is 40.
