NO. 27 THE DC SEPARATELY EXCITED SHUNT GENERATOR
d) Measure and record in Table 27-1 the armature voltage E_A for each of the listed field currents.

I_F (mA) E_A (V)
0 0
50 25
100 50
150 75
200 90
250 115
300 130
350 140
400 150

f) Can you explain why there is an armature voltage even when the field current is zero? Because the circuit is separated to the shunt field circuit. No matter what happens to shunt field circuit, armature voltage occurs.
5.c) Did the armature voltage reverse its polarity? Yes
6.c) Measure and record the armature voltage. E_A=125Vdc
d) Is the armature voltage approximately the same as in Procedure 4 except for reversed polarity? Yes
7.c) Did the armature voltage reverse its polarity? Yes
8.c) Measure and record the armature voltage. E_A=125Vdc
d) Is the armature voltage approximately the same as in Procedure 4 except for reversed polarity? Yes
10.c) Record the shunt field current I_F. I_F=390mA
11.b) Measure and record E_A and I_A for each of the resistance values listed in the Table.
