Question

What is the last step involved in the design of field regulators for shunt generators?

(a) calculation of the resistance of section

(b) calculation of the total field circuit resistance

(c) calculation of resistance of section

(d) resistance to be inserted

This question was addressed to me during an online exam.

My question is taken from Motor Starters, Calculation of Resistance Steps & Design of Field Regulators in chapter Design of Small Electrical Machines, Starters and Field Regulators of Design of Electrical Machines

Answer 1

The correct answer is (c) calculation of resistance of section

For explanation: 2 machines are considered in the design of field regulators for dc machines. They are the shunt generators and shunt motor. The last step is the calculation of resistance of section.
