    Can you get the power used from 1 hour meter reading?

    My bad.. One method is what I have described above.. another simple method is that you watch your meter for some time (say two minutes) and note the change in the meter reading of kWhr. Now divide that reading with the time and you will get the KWs you are using. e.g your meter shows a usage of...

    Can you get the power used from 1 hour meter reading?

    I think you want to say 200 kWhr (not kW).. If your meter is showing 200 kWhr in one hour then it means that you have used a total power of 200 kW in that one hour.. If you want to measure the power you are using at a particular instant then its a bit complicated.. For this you have to measure...

    Find the maximum power of power plant

    Homework Statement The daily load demand of a grid is given by P=Pmax * cos(pi*t/24). Here -12hrs ≤ t ≤ 12hrs. Maximum power occurs at (t=0) and minimum occurs at (t= ±12). A 10 GW hydro power plant with pump storage is available for base load operation. The turn-around efficiency of the...

    Power output of a solar panel if a complete row of cell is shadowed

    thanks delphi and cwatters.. have searched the web a lot in order to find an electrical circuit diagram for many cells connected in series or parallel but couldn't find one.. do you guys have any idea where can I find it?

    Power output of a solar panel if a complete row of cell is shadowed

    Oh. I was thinking that in practice all the solar cells are connected in series in a panel, and then you can connect these panels in series and/or parallel. Am I wrong? Another thing is how to represent them in a circuit diagram?

    Power output of a solar panel if a complete row of cell is shadowed

    Homework Statement I have to analyse the power output of a solar panel using a basic electrical engineering circuit analysis of a solar module if a complete row of solar cells in it is shadowed (For example, such shading might be caused by dust that slides down the surface of inclined panels.)...
