QUES: Currents induced into this winding provide the rotor magnetic field. The shape of the rotor bars determines the speed-torque characteristics. At low speeds, the current induced in the squirrel cage is nearly at line frequency and tends to be in the outer parts of the rotor cage. As the motor accelerates, the slip frequency becomes lower, and more current is in the interior of the winding. By shaping the bars to change the resistance of the winding portions in the interior and outer parts of the cage, effectively a variable resistance is inserted in the rotor circuit. However, the majority of such motors have uniform bars.

Where can variable resistance not be created?
What is the answer?
ANS: unanswerable
QUES: Chopin's music was used in the 1909 ballet Chopiniana, choreographed by Michel Fokine and orchestrated by Alexander Glazunov. Sergei Diaghilev commissioned additional orchestrationsfrom Stravinsky, Anatoly Lyadov, Sergei Taneyev and Nikolai Tcherepninfor later productions, which used the title Les Sylphides.

Who choreographed Chopiniana?
What is the answer?
ANS: Michel Fokine
QUES: The fast-growing I-4 corridor area, which runs through Central Florida and connects the cities of Daytona Beach, Orlando, and Tampa/St. Petersburg, has had a fairly even breakdown of Republican and Democratic voters. The area is often seen as a merging point of the conservative northern portion of the state and the liberal southern portion, making it the biggest swing area in the state. Since the late 20th century, the voting results in this area, containing 40% of Florida voters, has often determined who will win the state of Florida in presidential elections.

What does the I-5 corridor run through?
