Answer / mahesh sali

dc supply given to the x'mer , there is no flux produced
into the transformer due to the absence of frequency ,
cause will be damaged of insulation of x'mer and its get
overheated

Answer / naveen

it will lead to burning of transfotmer because there will
not be any secondary emf hence tranformer will work like a
load itself & due to overheating it will burn.

Answer / guest

When DC is supplied to a transformer the windings in the transformer will make it a electro magnet. There will be no
effect on the secondary but when the supply is interrupted a
voltage will be induced in the secondary.

when neutral will carry the current?what could be the magnitude?

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?
