Consider the following statements about the Squirrel cage rotor:
(A) One copper or aluminum bar is placed in each slot. All these bars are joined at each end by metal rings called end rings.
(B) It is possible to add any external resistance to the rotor circuit to have a large starting torque.
Then:
1
(A) is true and (B) is false
2
Both (A) and (B) are false
3
Both (A) and (B) are true
4
(B) is true and (A) is false
