Step 1 : Equivalent resistance

Let n be the number of resistors to be connected in parallel

Then, R1=R2=......=Rn=R=176 Ω

Now, 1Req=1R1+1R2+.....1Rn

⇒1Req=nR1=n176

⇒Req=176/n ....(1)

Step 2 : Applying Ohm's law

V=IReq

⇒220=5Req

⇒220=5×176/n (Using Equation (1))

⇒n=4

Hence, four resistors are required.
