Figure 5a (b) An AC source of 240 20" V, 50 Hz supplies three loads connected in parallel. The three loads are a 3.5 kW electrical heater, a pure inductive load of j24 $2 and a pure capacitive load of -j6 12, as shown in Figure Sb. Determine: (i) the resistance R of the heater, (ii) the current in flowing through the heater in phasor form; (2 (iii) the reactive powers Qu of inductive load and Qc of capacitive load; (6 (iv) the total apparent power ST. (V ) the power factor and state if it is leading or lagging. (2 heater R ZL Zc Figure Sb
