1. Following table, illustrate time x an employee spent in years for a typical company versus his/her hourly pay y in dollars. Find average amount of years employee spent in a company and average hourly pay. Also, find the coefficient of correlation between these quantities. X (time in years) 3 4 5 10 15 20 Y (hourly salary) 15 17 22 33 37 40
Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
