THREE resistive loads are connected in star to a three$-$phase, $4-$wire, $220$ V supply. The load values are:

$R_R=56,R_S=91,R_T=33$

$($a$)$ Calculate EACH of the following:

$($i$)$ the current in EACH load;

$($ii$)$ the current in the neutral;

$($iii$)$ the total power supplied.

$($b$)$ Sketch, approximately to scale, a labelled phasor diagram of the load and neutral currents.
