Good Day...Guys can you give me idea about VoltAmpere ( VA ), I know that the Power = Volt x Ampere = Watts but I noticed that some equipment have different amount of power and VoltAmpere (VA ) for example i saw last week a medela suction machine have a rating of ( 1500Watts and 80VA)..I cant remember the exact value of VA but im sure the value was to far on 1500 watts rating..Are they different
