1. A factory has a 240-V supply from which the following loads are taken:

Lighting: Three hundred 150-W, four hundred 100 Wand five hundred 60-W lamps Heating: 100 kw
Motors: A total of 44.76 kW (60 b.h.p.) with an average efficiency of 75 percent

Misc.: Various load taking a current of 40 A.

Assuming that the lighting load is on for a period of 4 hours/day, the heating for 19 hours per

day and the remainder for 2 hours/day, calculate the weekly consumption of the factory in kWh when working on a 5-day week. What current is taken when the lighting load only is switched on?​
