What is the Secondary Voltage of This Transformer?

[Natalia]

A transformer has 10,000 windings on the secondary side, 200 on the primary side. If the primary voltage is 110V and the primary current is 5A, what is the secondary voltage?

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?

There are no choices. I don't want the answer, just an ideia from where to start lol

That's an exaggeration. It's at least several hundred volts less than infinite

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.

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

You know primary volts and amps. Once you've figured out the turns ratio you'll be able to calculate secondary volts and amps.
