Q2. What is oer unit slip
Ans. 
Unit slip is the difference between synchronous speed and rotor speed in an induction motor.
• Unit slip is expressed as a fraction or percentage.

• It is used to calculate the rotor speed of an induction motor.

• Unit slip is necessary for determining the torque and efficiency of the motor.

• For example, if the synchronous speed of a motor is 1800 RPM and the rotor speed is 1750 RPM, the unit slip would be 0.0278 or 2.78%.
