If it operates on 220V line, its power is P=V^2/R=151250W !

However, If the problem is given like , "you have a 100W with resistance 0,32 ohm what's the current? that'd come up as

I=Sqroot(P/R)=17,6A

First result doesn't make sense, or doesn't look "realistic" but the second one does. But they both stem from the same formula: P=IV

Why does it seem to me that these two formulas does not reconcile with each other?
