Q2: The two loads in the circuit shown below can be described as follows: Load 1: Absorbs an average power of 60 kW and delivers 70 KVAR magnetizing reactive power. Load 2: Has an impedance of 24 +j 7. The voltage at the terminals of the loads is 2500V2 cos(120nt) V. Answer the followings: (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 seurce voltage?
