Question 3

 

A d.c. shunt-wound generator has armature resistance of 0.125 Ω and a shunt field resistance of 60 Ω. If the generator delivers 100 A at 240 V, calculate the:

  1. field current;
  2. armature current;
  3. generated e.m.f.

Observation

      

The expected responses were:

 

 

Many of the candidates performed well in this question except those that did not use correct symbol for inductance and the sinusoidal voltage.
