It's pretty much infinite. Is that one of the choices on this homework question?
Oh, did you read the PF Homework rules under INFO when you joined?

That's an exaggeration. It's at least several hundred volts less than infiniteberkeman said:

It turns out that a transformer has a characterisitic of Volts per Turn is a constant for both the Primary and Secondary. You have all the information for the Primary, and half the information for the Secondary. Try making use of it.

- Is it a step-up or a step down transformer? Why?
- What is the turns ratio? Show calculation.
- What is the relationship between power (volt-amps) on the primary side versus the secondary side?
