How to Calculate Electrical Energy Consumption for 230V / 50Hz / 1Ph Apparatus?

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 ;)

If you have access to IEEE Xplore, you might look up " Methods for electric power measurements". The URL is http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=985253. The paper discusses electric meter calculations, but I think it directly relates to your question.

What is the Ouptu work to be done? You can work backawrd from that.
