Concept explainers
A transformer has an input of 9 volts and an output of 36 volts. If the input is changed to 12 volts, show that the output would be 48 volts.
To Show: the output is
Answer to Problem 55A
The output voltage is
Explanation of Solution
Given:
Transformer output voltage
Transformer input voltage
Changed input voltage
Formula used:
Calculation:
The transformer voltage remains constant. Assuming no losses in the transformer and input voltage is proportional to output voltage.
Considering the concept of transformer voltage remains constant.
Equation becomes,
Hence, proved
Conclusion: Considering the voltage ratio in the transformer the voltage is
