calculate energy

[TaKiMi]

Hello guys...

I have one question..How do you calculate the electrical energy using labview? Anyway,I get the formula energy W=P * t. n P must be constant over the time interval under consideration.So...how can I multiply P with t, that t in minutes for example.That mean, when the prog running, W will be calculating every minutes it works..Thank u very much

You need to integrate the data to get the energy value.

There is a point by point integration vi in the following pallette:

Signal Processing - Point By Point - Integral & Differential Point by Point

Hello ssk....do you have any other example how to use this.What exactly initial condition can be detemined.Which want vi from point by point can be used..Integral or derivative..thank u very much.

Hi,

 You could record the voltage and current points,then make the mean of V and C.

 Then the P=V*I,W=P*T.
