Answer 1

Answer #1

ns/np = ip/is

is = ip(np/ns)

ns>np

so is<ip

if np>ns

then is>ip

If this ratio is less than unity, n < 1 then ns is greater than np and the transformer is classed as a step-up transformer

If this ratio is greater than unity, n > 1, that is np is greater than ns, the transformer is classed as a step-down transforme
