Three loads are connected in parallel to a 120?0° V rms source. Load 1 absorbs 60 kVAR at pf =0.85 lagging; load 2 absorbs 90 kW and 50 kVAR leading; and load 3 absorbs 100 kW at pf = 1. (a) Find the equivalent impedance. (b) Calculate the power factor of the parallel combination. (c) Determine the current supplied by the source.

An international aerospace contractor has been asked by a municipal police department to estimate and analyze the life cycle costs for a proposed drone surveillance system to monitor traffic patterns and congestion within the central thoroughfares of the city. The list of items include the following general categories: R&D costs (R&D), nonrecurring investment costs (NRI), recurring investment costs (RI), scheduled and unscheduled maintenance costs (Maint), equipment usage costs (Equip), and disposal costs (Disp). The costs (in $ million units) for the 20-year life cycle have been estimated. Calculate the annual LCC at an interest rate of 7% per year.
