Explain Squirrel- cage rotor
Squirrel- cage rotor having of a slotted laminated core of sheet-steel. The slots of the rotor are not always parallel to the slots on the stator, but they are given a twist called as skew. (Skew decreases noise, eliminates cogging and enhances the starting torque). The windings are placed in the slots. Every slot carries a thick copper or aluminum bar. These bars are short-circuited on either end by a solid copper or aluminum ring known as end-ring. Most of the 3-phase induction motors are of squirrel cage type, due to its rotor is simple and rugged in construction and is cheaper.
1) Consider 2kg mixture of H 2 and N 2 ideal gases inside a closed piston-cylinder device at 150kPa and 100o C. This mixture has 0.4 mole fraction of H 2 . This mixture undergoes

Earth is losoing heat in order balance the input outpout . But where is going that heat since there is nothing out to get it. Billions of stars are loosing heat the same way and so
1. You now pass the signal + interference through a 2-section 1.0 kHz low pass filter with a rolloff of 40 dB/decade. Make a plot of the waveform of the filter output over the time

A 20 Ω non-reactive resistor is connected in series with a coil of inductance 80mH and negligible resistance. The combined circuit is connected to a 200V, 50Hz supply. Calcula
Hello! I would like to ask if there is a job in Physics which is 24/7 Question Answering/problem solving and if any, I would like to apply for it. Thank You Prerak Dhawan
Optical interference process is broadly divided into two categories namely (i) division of wave front (ii) division of amplitude. Give one example for each category of interference
