7) A single-phase 220 V, 50 Hz source supplies power to a seres R-L circuit consisting of R=10 Ohms and L=40 mH. a. Determine the power factor of the circuit and state whether it is lagging or leading b- Determine the real and reactive power absorbd by the load C. Calculate the peak magnetic energy Wm stored in the inductor by using Wm=L(Irms)2 and check whether the rective power Q=wW is satified (Note: The instataneous magnetic energy storage fluctuates between zero and the peak energy. This energy must be sent twice each cycle to the load from the source by means of reactive power flows) r - Con k high
