why transformer donot allow the dc?

Answer Posted / balaji

IN AC SUPPLY PRODUCED HIGH CURRENT ALSO SO DC CANNOT
PRODUCED HIGH CURRENT FOR E.G DC SUPPLY MAX CAPACITY BELOW
500 AH IN SINGLE BATTERY. IN AC ALTERNATOR PRODUCED MEGA
CURRENT BUT DOMESTIC USE 230V ONLY SO DECREASE THE VOLTAGE
RANGE IS USED FOR TRANSFORMER. 63/33KV AND 33/11KV AND
11KV/430V. PRODUCES THE CURRENT IN ALTERNATOR IS VERY HIGH
TRANSMISSION LINE ITS USED HIGH VOLTAGE LINE. IN DC SUPPLY
IS USE FOR MARINE RAILWAY SIGNAL ETC IN DC SUPPLY PRODUCES
THE BATTERY BUT CHARGE THE BATTERY WANT AC SUPPLY.

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?
