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.
With that purpose was famous Davisson-Germer experiment with electrons performed? Name the type of communication in which the sign is a discrete and binary coded version of the
Light is quantized. Photons are light quanta. It has zero REST mass. Therefore, it always travels at maximum speed permitted by relativity.
Presume you are asked to find the electric field at point P whose coordinates are (L, y) for the case of a consistent line segment of charge which extends from x=0 to x=L on the x

A negative point charge of 10 -6 coulomb is located in air at the origin of a rectangular coordinate system. A second negative point charge of 10 -4 is situated on the positive x
when told that a diffraction grating has 80 lines per mm we need to work out what 1 line would equal. I have the solution but i cannot figure out how they got 1 line to equal 1x10
what to right
