## Homework Statement

What should the primary voltage be changed to in order to produce a secondary current of 10 A, given that the V / I ratios for the coils do not change?

Current ratios that I have calculated so far are as follows:

Np (200) Vp (1200) Is (15)

Ns (40) = Vs (240) = Ip (3)

## Homework Equations

If focusing on just the IpVp = IsVs ratio - then the solution would be...

## The Attempt at a Solution

The primary voltage would be changed to 800 V according to my calculation, I would appreciated your advice.
