R=V/I
=220/5 =44 Ω
Let 'n' is the number of 440 Ohm resistors connected in parallel to achieve overall 44 Ohm resistance.
Using the formula of equivalent resistance for resistors connected in parallel we get n/440 = 1/44 [(1/R)=(1/R1)+(1/R2)+.... ;
R is equivalent resistance, Ri is the resistance of i-th resistor in parallel]
So clearly n=10
