R= 240
V= 220
and t= 10 minute 10 ×60 =600second
so , the Electrical energy = vIt and we have to find I means current.=V/R=220/240= 11/12
So, I = 11/12.
then put the value of I in electrical energy formulae. = 220× 11/12 × 240= 220×10 × 11 = 2200× 11 = 24200 this is your answer please mark as brainlist
