What is the second step in the design of the field regulators for dc machines?
(a) calculation of the resistance of section
(b) calculation of the total field circuit resistance
(c) calculation of the field circuit resistance
(d) resistance to be inserted
The question was posed to me at a job interview.
The origin of the question is Motor Starters, Calculation of Resistance Steps & Design of Field Regulators topic in section Design of Small Electrical Machines, Starters and Field Regulators of Design of Electrical Machines
