The formula to calculate the Slip (s) is:
\[ s = \frac{R}{X} \]
Slip in Induction Motor is the relative speed between the rotating magnetic flux and rotor expressed in terms of per unit synchronous speed. It is a dimensionless quantity. Resistance is a measure of the opposition to current flow in an electrical circuit. Reactance is defined as the opposition to the flow of current from a circuit element due to its inductance and capacitance.
Let's assume the following values:
Using the formula:
\[ s = \frac{14.25}{75} \approx 0.19 \]
The Slip is approximately 0.19.
