Answer to Question #279001 in Classical Mechanics for Jjj

Question

The emf induced in the armature of a shunt generator is 596 V. The armature

resistance is 0.1Ω

(a) Compute the terminal voltage when the armature current is 460A.

(b) The field resistance is 110Ω. Determine the field current, and the current and power delivered to the external circuit

Answer 1

a)

$i=\frac{\varepsilon }{\frac{\varepsilon}I-r}=500~mA,$

b)

$I_c=\frac{\varepsilon }R=5.4~A,$

$P={I_c^2}R=3.2~kW.$
