1.	How should the rotor voltage be with respect to the high voltage and large machines?(a) low(b) moderate(c) high(d) very highThis question was posed to me during an interview for a job.The query is from Design of Wound Rotor topic in portion Three Phase Induction Motor of Design of Electrical Machines
Answer» RIGHT answer is (C) HIGH Best explanation: The high voltage and large machines should have high rotor voltage. If the rotor voltage is kept low, the rotor current BECOMES large, involving use of large CONDUCTOR sections.
