Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Torque of induction motor is
i.e, Torque is directly proportional to square of the voltage
∴ T ∝ V2
Calculation:
Case 1:
Torque = T1
Voltage = V1
Case 2:
Reduction in supply voltage by 10%
Torque = T2
Voltage = V2 = 0.9 V1
T2 = 0.81 T1
% Change in T =
Therefore, the correct answer is an option (2)
