QUESTION 3 a) Draw a labeled circuit diagram for; a (i) a dc generator, (ii) dc motor a b) A 280-V dc machine has an armature resistance of 0.20 2. If the full-load armature current is 40 A, find the induced emf, E when the machine is operated as (i) a dc generator, (ii) a dc motor a dc c) Draw a labeled circuit diagram for; (i) a dc shunt motor, (ii) series motor, (iii) a separately excited dc motor d) A 20-kW, 280-V dc shunt machine has armature resistance of 0.15 12 and a field resistance of 100 22. Determine the total armature power developed when operating as (i) a dc generator delivering 20 kW output power, (ii) a dc motor taking 20 kW input power.
