Consider the following statements:

In a 3-phase induction motor connected to a 3-phase supply; if one of the lines suddenly gets disconnected, then the

1. Motor will come to a standstill

2. Motor will continue to run at the same speed with line current unchanged

3. Motor will continue to run at a slightly speed with increase in the line current

4. Rotor current will have both of sf and (2-s)f component frequencies where s is the slip and f is the supply frequency

Of these statements:

(a) 1 and 4 are correct

(b) 1 and 2 are correct

(c) 3 and 4 are correct

(d) 2 and 3 are correct
