A $3-$phase load is supplied from the secondary of a star connected

transformer with a line voltage of $400$V$.$ Each phase of the load has an

inductive reactance of $10$ in series with a resistance of $24.$ Determine the

following quantities, when the load is STAR connected and DELTA connected

i$)$ Voltage across each phase of the load

ii$)$ Current in each phase of the load

iii$)$ Power taken from the supply $($VA$,$ W$)$

iv$)$ Power Factor
