That means Power (measured in watts) is voltage (V) times times current
(I) measured in amps.
In very very crude and ugly terms, that means (using your water
The amount of water that has flowed out of your wall socket is the water
pressure times the size of the pipe.
That's really ugly as analogies go but something to keep in mind is that
