Why we Do not connect the windings of the
motor in delta? & what would happen if we
do that?
I mean the winding themselves not the
three lines that are coming to the motor?

Answer Posted / sarmadahmed

One reason is because we need a neutral for grounding the motor so the winding of motor is connected in Y.

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?
