The two loads shown in Fig. P10.21 can be described as follows: Load 1 absorbs an average power of 10 kW and delivers 4 kVAR of reactive power; Load 2 has an impedance of (60 + j80) . The voltage at the terminals of the loads is 1000V/2 cos 100mt V. a) Find the rms value of the source voltage. b) By how many microseconds is the load voltage out of phase with the source voltage? c) Does the load voltage lead or lag the source voltage?

Please show all steps clearly, thank you

10.21 The two loads shown in Fig. P10.21 can be described as follows: Load 1 absorbs an average power of 10 kW and delivers 4 kVAR of reactive power; Load 2 has an impedance of (60+ j80) 2. The voltage at the terminals of the loads is 1000√2 cos 100mt V. a) Find the rms value of the source voltage. b) By how many microseconds is the load voltage out of phase with the source voltage? c) Does the load voltage lead or lag the source voltage?
