Electrical Multiple Choice Questions
Electrical Multiple Choice Questions 1) Which of the given motor has insufficient starting torque at full load speed with the same H.P. ratings? Three-phase Induction motor Shunt motor Synchronous motor Differential compound motor Answer: Option d. Explanation: Differential compound motor has poor starting torque at full load speed with same H.P. ratings because its shunt fields restrict series field. The primary reason for the less starting torque than the motor is reduced field flux. The Dc compound motor is a type of self-excited motor, but it is a compound of both series and shunt field coils connected to the armature winding. A series field winding connected in series with the armature and a shunt field winding connected in parallel to the armature. 2) Which of the given networks are based on the compensation theorem? Unilateral network Bilateral network Linear and non-linear network Distributed network Answer: Option c. Explanation: Linear and non-linear network is bas...
