It's on the light bulb. If you get a light bulb labeled 100W, it should use approximately 100W.Where did you get the value of P (power) ?
What do you mean by load?It's on the light bulb. If you get a light bulb labeled 100W, it should use approximately 100W.
More broadly, the amount of current that flows through an outlet is determined by the load. In this case it's 100W, but that depends on what's plugged in.
Load is the cumulative resistance of the entire circuit (not the sum of all resistors, but using the proper formulas for serial and parallel parts of the circuit). In a light bulb, it's already labeled for you. Since you know it's an 18W bulb, and you know the outlet is 220V, just plug those into your formula P=VI. 18=220*I. Now, to solve for I, divide both sides by 220. I=18/220=0.0818A.What do you mean by load?
It's a bulb with 18W.
