    2.What's single phase and 3 phase?

    3.What's 11kvA means?

    Hi,

    1) Phase is which has electric power (electron or voltage) passing through

    2) Neutral is drawn seperately, which doesnt have any current

    3) 3 Phase are the phases to be drawn seperately which should not be merged

    4) 11 kva means 11000 volts.

    1 phase is electronagative body  and neutral is electropossitive body

    when we connect any electric load between them the electrons flowing through the load and u know

    force x displacement =work than

     

    flowing current x voltage across load = power
