    Hi everybody,

    I got this task from my teacher: "A load takes a current of 20 A at a phase angle of 70(degrees) lagging from a 240V,50Hz supply."
    a) Draw the phasor diagram showing the supply voltage V, the supply current I(rl), the phase angle and the power factor.;
    -----------------------------------------------

    I really need help with the phasor diagram part. Because I have no idea how to start it. Please can somebody just put me on the right track.

    Thanks.

    hi there

    so if you are learning this subject at the moment, you must some ideas on where to start
    show us what you have figured out so far and you will be guided from there

    Surely if your tutor is getting you to do homework on this, it must have already been covered in class ?
    What does your course textbook have to say on the subject ?

    cheers

    While it is certainly possible to draw two lines with a 70 degree angle between them, is it really a phasor diagram if the units are not the same? One characteristic of a phasor diagram is the ability to add individual phasors to obtain a resultant phasor. How would that be possible if one phasor is voltage and the other is current?

    The thing is, I am doing BTEC courses and everything I do is based on independent research.
