A double$-$wound, $1-$phase transformer is required to step down from $1900$ V to $240$ V$,50-$Hz$.$ It is

to have $1\mathrm{.}5$ V per turn. Calculate the required number of turns on the primary and secondary windings

respectively.

The peak value of flux density is required to be not more than $1\mathrm{.}2$ Wb$/$m$2.$ Calculate the required

cross$-$sectional area of the steel core. If the output is $10$ kVA, calculate the secondary current.
