I need a solution within 15 minutes a) A 30 hp, 240 V, 19.167 rps DC shupt motor operating at rated conditions has an efficiency of38.5%. The armature resistance and field resistance are 0.096 N and 93.6 Q respectively.Determine:the mechanical developed power and torque.ii)i)the external tésistance required to limit the starting torque to 200% of rated torque." the toad /torque is now reduIced to 40% of rated torgue find the new armaturecurrent add new operating speed.D) There are several ways for testing DC machines, mention them and explain one of them indetail with illustrations.

As per the guidelines of Bartleby we supposed to answer first question only.

2. A bank of nickel-cadmium cells is used as the emergency lighting supply for a hospital. There are 100 cells connected in series and each has an A-hr rating of 120 A-hr. The bank has to be replaced, and the manufacturer is no longer supplying nickel-cadmium cells. It is decided to replace the cells with lead-acid cells. How many lead-acid cells will be required if each has an A-hr rating of 60 A-hr, and how should they be connected?
