Q3) Three resistive loads of 50 Ω, 40 Ω, and 30 Ω are connected respectively in star to the R, S, and T phases of a three-phase, 4-wire, 415 V, power supply.

(a) Determine EACH of the following:

(i) the current in each load; (5)

(ii) the current in the neutral wire; (5)

(iii) the total power supplied. (2)

(b) Sketch, approximately to scale, the phasor diagram of the load and neutral currents. (4)
