A. equal to the power rating of the machine
B. 1/2 to 2% of the rated power of the machine
C. greater than the power rating of the machine
D. less than the power rating of the machine
Answer:A
The power rating of the field winding is ___________
A. equal to the power rating of the machine B. 1/2 to 2% of the rated power of the machine C. greater than the power rating of the machine D. less than the power rating of the machine
Explanation: The power input to the DC field winding is dissipated as i2R loss in the field winding (once the required field current is established). 8. What is the reason behind armature structure for both DC and AC machines being laminated?
