Household appliances - refrigerator, lamp, and microwave are connected to the voltage sources as shown in the circuit. The current that flows through Refrig is 8.5A, and the refrig's impedance (Zrefrig=Rrefrig+jXrefrig) has phase of 45 degree. Also, the lamp and microwave dissipates 100[W] and 12[kW], respectively. (Note, all current and voltage values are rms values, and the circuit is a 3 phase circuit.) 1. Find I1, I2, I3. 2. Find the average power (P) and reactive power (Q) dissipated in each of the appliances. 3. Find the power factor of all three appliances altogether. 4. 20 ohm resistance is added to the neutral line. Find the voltage across the lamp. (Note: range in the circuit is the microwave)
