The transformer equation:

VpVs=IsIp=NpNs

Relating voltage and the number of turns, then solving for Vs:

Vs=VpNsNp

The rms secondary voltage is:

Vs(rms)=VpNs2Np

#1

Vs(rms)=(240)(2000)2(1000)

vs(rms) = 339.4 V

Problem Details

Rank the transformers on the basis of their rms secondary voltage. Rank from largest to smallest. To rank items as equivalent, overlap them.

#1

Vp=240V
Np=1000turns
Ns=2000turns

#2

Vp=480V
Np=4000turns
Ns=2000turns

#3

Vp=480V
Np=2000turns
Ns=1000turns

#4

Vp=120V
Np=500turns
Ns=2000turns

#5

Vp=240V
Np=1000turns
Ns=500turns

100 A of rms current is incident on the primary side of each transformer.
