The rotor of a wound-rotor induction motor is rewound with twice the number of its original turns,with a cross-sectional area of the conductor in each turn of one-half the original value. Determine the ratio of the following in the rewound motor to the corresponding original quantities:

(a) Full-load current.

(b) Actual rotor resistance.

(c) Rotor resistance referred to the stator.

Repeat the problem, given that the original rotor is rewound with the same number of turns as originally, but with one-half the original cross- section of the conductor. Neglect the changes in the leakage ?ux.
