An electric iron draws a current of 4 A from 220 V supply line. When voltage of supply is changed, then iron draws a current of 2 A, what is the new

voltage applied?


WHEN current(I)= 4A, V=220v, then R=220/4= 55ohm. now in electric iron resistance will remain same so using ohm's law, v/2=55, so new voltage will be 110v
