  1. Questions about shunt motor

    1. The problem statement, all variables and given/known data
    Good evening everyone, I've got the following question :

    2. Relevant equations

    3. The attempt at a solution
    Lets see,, I solved until part (e) and I didn't understand the rest.
    My questions are :
    , does it mean P = E(armature)*I(armature) ?? and BTW the word
    means output ??
    (f) what does
    mean ?? what should I do to make the load half ??
    does it equal 0 ?? and if it does why and if not why not ??

    these are my questions for now ,, I'll try solving (j) after solving those ,, so I need help :smile:
