decreases the rotor current
increases the rotor current
rotor current becomes zero
rotor current rernains same
Answer is Right!
Answer is Wrong!
The correct answer is: A. decreases the rotor current.
When resistance is inserted in the rotor of an induction motor, the rotor current decreases. This is because the resistance in the rotor circuit causes a voltage drop, which reduces the current flowing through the rotor. The reduced current causes a decrease in the torque developed by the motor.
Option B is incorrect because the rotor current decreases, not increases.
Option C is incorrect because the rotor current does not become zero.
Option D is incorrect because the rotor current decreases, not remains the same.
