Chapter 5, Problem 1RQ

An AC power source is connected across 325 turns of an autotransformer, and the load is connected across 260 turns. What is the turns ratio of this transformer?

To determine

The turns ratio of the transformer.

Explanation of Solution

Given:

The number of turns in connection with the power source $\left(N_1\right)$ is $325$.

The number of turns in connection with the load side $\left(N_2\right)$ is $260$.

Calculation:

Calculate the turn ratio $\left(N_T\right)$ using the relation.

  $\begin{array}{c}{N}_T=\frac{N_2}{N_1}\\ =\frac{325}{260}\\ =1.25\end{array}$

Thus, the turns ratio for the transformer is $\underset{\_}{1.25}$.
