How many 176W resistors (in parallel) are required to carry 5 A in 220 V line?

Here, I = 5A, V = 220 V.

Resistance required in the circuit, R = V/I = 220V/5A = 44 W, Resistance of each resistor, r = 176 W

If n resistors, each of resistance r, are connected in parallel to get the required resistance R, then R = r/n    or n  = r/R   = 176/44 = 4
