I'm surprised someone gave the guy above me a thumbs down, considering he's RIGHT. it's not specified if the circuit is AC or DC. P = VI only holds true in DC circuits. AC circuits are a totally different monster, where you also have complex power (S=VI*), apparent power ( |S| ), reactive power (the complex portion of complex power), and average power (the real portion of complex power).

The definition of 1 watt is the power from 1 volt causing the flow of 1 amp.
Just take the voltage and multiply it by the current.
So 110 x .5 = 55 watts. It is as easy as that.

If the load is a resistence ,watt = V*I = 55 watt

The above answers are true for DC (Direct Current) circuits or for single phase AC circuits when the Voltage and Amperes are expressed in RMS units. Otherwise more details are required to solve it.
