Electrical Energy calculation

    How do I calculate the consumption of energy for an apparatus with these characteristics: 230V / 50Hz / 1Ph ?

    You can't. That's just the type of electricity it requires, not the quantity. You need the amperage, which you then multiply by the voltage.

    better toss in power factor as well as time as factors if you want energy consumed.

    i know that i need the amperage...i thought there's another way to calculate the energy. thanks anyway ;)
