What is the voltage output of a 2,400V transformer with a 5:1 step down ratio?

• A. 120V
• B. 480V
• C. 1,200V
• D. 2,400V

Answer: (B)

To determine the voltage output of a transformer with a 5:1 step-down ratio, you need to divide the input voltage by the step-down ratio. In this case, the input voltage is 2,400V, and the transformer transforms this voltage down by a factor of 5. Performing the calculation: \[ \text{Output Voltage} = \frac{\text{Input Voltage}}{\text{Step-down Ratio}} = \frac{2400V}{5} = 480V \] This calculation shows that a transformer with a 5:1 step-down ratio takes the high voltage (2,400V) and reduces it to 480V, which represents the voltage you would measure across the secondary side of the transformer. Therefore, the output voltage is indeed 480V, making it the correct answer.
