To test Transformer we give HT side 440V to see wheather
that it is producing 17.6V on LT to verify Voltage ratio is
correct or not but when we give the 440V voltage to LT side
then what will happen to HT voltage ?

For ratio-test,the second answer may be correct.
But at the same time,if we apply high voltage in LV
side (in ratio-test also)for a longer period (in seconds),
LV winding cannot withstand, result in insulation break-
down,blown-out of fuses.
generally ratio-test is conducted with the
specified (allowable) voltage magnitude.so,practically this
much of voltage is not applied for LV side.I hope,this
answer will be correct.

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?
