What happens when the starter takes up metallic resistance?
(a) voltage fluctuates from high to low
(b) voltage fluctuates between fixed upper and lower limits
(c) current fluctuates from high to low
(d) current fluctuates between fixed upper and lower limits
I had been asked this question at a job interview.
Origin of the question is Motor Starters, Calculation of Resistance Steps & Design of Field Regulators in division Design of Small Electrical Machines, Starters and Field Regulators of Design of Electrical Machines
