    Re: what is difference between.....

    Hello !

    1. Divergence is an opertator of transformaing a vecotr to scalr (del(A))
    and Curl is vector multiplication of the del op. with any given vector: del X A
    (the del op. is called also sa nabla and its defined is the parlty derivative of the x, y and z componnent).
    the reusltent is a vector which prependicualr to the two multiplied vectors (in our case the del op. vector and the A vector)

    2. The Stoke's Theoremrelates a clused line integration to a surfcace area bounding it.
    and the Divergence Theorem relates the closed surface of a body to its volume by the div. op.

    About the 3rd pair - I don't know !

    Hoped I helped !

    3. Motional and transformer EMF:

    Motional EMF is the emf induced due to the relative motion between magnetic flux lines (whether of fixed field or not) and a conductor, [i.e. like moving a coil in a magnetic field, like that which is induced in a generator]; while the transformer emf is the induced emf by electromagnetic couplying between two objects, which don't move relative to each other, due to time-varying current, volt or magnetic field in one of the objects.[i.e. Like that in the transformer]
    :D
