extra credit (5 points) a 120/240-volt service, single-phase electrical system is shown in the drawing below. if the load in circuit 1 (connected between line 1 and the neutral) is 1,500 w, what is the current for line 1? if the load in circuit 2 (connected between line 2 and the neutral) is 1,200 w, what is the current for line 2? what is the combined neutral current? the power factor for this system is 90%. make sure to show all of your work.
