I think Pratik has given the exect answer. I wish to add
one more thing during closing of a circuit breaker. When we
close the breaker, there is rebounses of the contacts( 5-6
rebounces are normal in VCB). During transient state (Plus
fault) there is a chance of melting and welding of contacts
hence breaker making capacity is always required high.

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?
