Let the total number of resistors be x.
Given that:
Current I = 5 A and Potential Difference V = 220 V
According to Ohm’s law, V = IR

Now for x number of resistors of resistance 176 Ω, the equivalent resistance of the resistors connected in parallel is 44 Ω.

Therefore, 4 resistors of 176 Ω are required to draw the given amount of current.
