Determine phase of a delta-connected load, Physics

Assignment Help:

Each phase of a delta-connected load comprises a resistance of 30Ω and an 80µF capacitor in series.

The load is connected to a 400V, 50Hz, 3-phase supply.

Calculate

(a) the phase current,

(b) the line current,

(d) the kVA rating of the load. Draw the complete phasor diagram for the load.
