.
Substituting the given values,
Part (b) To Determine:
If the transformer is step-up or step-down.
Answer to Problem 30P
Solution:
The transformer is a step-down transformer
Explanation of Solution
Given Data:
Input current,
Input voltage,
Output current,
Formula Used:
Voltage ratio,
Where, and is the primary and secondary voltage respectively.
Calculation:
We know that the ratio of primary to secondary voltage of the transformer,
.
Substituting the given values,
Since the voltage is dropping down, the transformer is a step-down transformer.
