What is the voltage ratio of a transformer with a primary voltage of 120 volts and a secondary voltage of 24 volts?

To find the voltage ratio of a transformer, you compare the primary voltage to the secondary voltage. The voltage ratio is expressed as the primary voltage divided by the secondary voltage.

In this case, the primary voltage is 120 volts and the secondary voltage is 24 volts. By calculating the ratio:

Voltage ratio = Primary voltage / Secondary voltage

Voltage ratio = 120 volts / 24 volts = 5

This results in a voltage ratio of 5:1, indicating that for every 5 volts in the primary winding, there is 1 volt in the secondary winding. This means the correct answer reflects the relationship between the two voltages in the transformer accurately. Understanding this concept is crucial for working with transformers, as it helps in determining voltage conversions in electrical systems.
