4d-4f answered please

4) Power is being supplier to an industrial site. The current into building 1 is i, = 100 cos(120nt + Amps. The current into building 2, which has a large solar farm on the roof, is i, = 3n 300 cos ( 120nt + ") Amps. a. What frequency in Hz is being provided? b. The current iline in the line that feeds both the two buildings must be the sum of the two currents. What is this current? с. What is the time shift of this current? d. By hand, sketch a plot of all three currents. Be sure to label it so that the three different amplitudes and 3 different phase angles are clear. e. Using a software tool, confirm your work to this point and reproduce your plot. f. A third building is being added to the site. If it needs 200 Amps of current at the same frequency and is added to the same line, what phase angle for building 3 would allow the current in the power line (the sum) to have a phase angle as close to t as possible? (another way of saying this is that you want to reduce the imaginary part of the sum of the building currents by as much as possible.)
