Question

A transformer operating at primary voltage $8 \,\mathrm{kV}$ and secondary voltage $160 \mathrm{~V}$ serves a load of $80 \mathrm{~kW}$. Assuming the transformer to be ideal with purely resistive load and working on unity power factor, the loads in the primary and secondary circuit would be

$800 \,\Omega$ and $1.06 \,\Omega$
$10 \,\Omega$ and $500 \,\Omega$
$800 \,\Omega$ and $0.32 \,\Omega$
$1.06 \,\Omega$ and $500 \,\Omega$
