1.	When does the starter take up liquid rheostat?(a) when the resistance can be varied heavily(b) when the resistance can be varied gradually(c) when the resistance cannot be varied(d) when the resistance should not be variedThe question was asked during an interview for a job.I want to ask this question from 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
Answer» Right CHOICE is (b) when the resistance can be varied gradually Easy explanation: The starter ACTUALLY PICKS up either liquid RHEOSTAT or metallic resistance during its operation. The starter takes up liquid rheostat during the situation where the resistance is gradually varied.
