what becomes of the voltage if we use 2 resistors of 4w in parallel?

The 4 Watts is the rating not the wattage going through it
The voltage across the parallel circuit is the same as the source across it both resistors get the same voltage

V = √P/r
you need to know r , otherwise u cant say the value of V

For the formula of power P=(V^2)/R, the power is 4 Watt each. The voltage can be found if you know the resistance.

Too lazy to even post the full question when cheating with Yahoo Answers. What becomes of you? FAIL.

what a dumb question , its the ohm that matter , not if there 4 watts ..

it will be the same as when you use a 2 ohm resistor

If you use 2 resistors in parallel the voltage across them is the same.
If they are the same resistance then the currents are equal and they dissipate the same power. If the resistances are different then the currents and power dissipation's will be different but the voltage's will still be the same.

you are missing part of the question, this makes no sense.
wattage RATING becomes 8 watts, but actual watts dissipated depends on applied voltage.
Voltage is whatever you apply.

Assume you mean 2 resistors of 4Ω in parallel. 4*4/(4+4) = 1/(1/4+1/4) = 2Ω
Just like 3 9Ω's in parallel = 1/(1/9 + 1/9 + 1/9) = 1/(3/9) = 9/3 = 3Ω

Use Ohm's Law for the answer.
