The two loads shown in (Figure 1) can be described as ollows: Load 1 absorbs an average power of 10 kW and delivers 4 KVAR of reactive power; load 2 has an mpedance of (60 + j80) N. The voltage at the terminals of the loads is 1500/2 cos(100rt) V. 0.5 N j0.05 2 L2 Find the rms value of the source voltage. Determine by how much time the load voltage is out of phase with the source voltage by finding the value of (Ov, – Ov,)/w, where Oy, and Ov, are the phase angles of the voltages VI, and Vg respectively, and w is the angular frequency of the voltages. Does the load voltage lead or lag the source voltage?
