Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFTerminal voltage (V) =230 volts
Generated voltage (Eg) = V + (Ia × Ra)
Armature current = Ia = load current + Ish
Field current = Ish
Armature resistance = Ra = 0.1 ohms.
Field resistance = Rsh = 50 ohms.
Ish = 4.6 Amps
Ia =load current + Ish
Ia = 450 + 4.6 = 454.6 Amps.
Eg = V + (Ia × Ra)
Eg = 230 + 454.6 × 0.1
Eg = 275.46 Volts.
