    If there wasn't any battery before, then there was no current

    in the circuit before, and there IS one now. That's just about

    the greatest change possible.

    If there WAS a battery there before and you added another one

    in series with it, then there are a few different possibilities for the

    effect on the current in the circuit:

    - - If the new battery has the same voltage as the original one,

    AND you connect the new one so that they're both in the same

    direction, then the current in the circuit will become double the

    original current (twice as much as it was before).

    - - If the new battery has the same voltage as the original one, AND

    you connect the new one so that they're in opposite directions, then

    the two batteries cancel each other, the total voltage becomes zero,

    and the current in the circuit completely disappears.

    - - If the voltage of the two batteries is different AND you connect

    the new one so that they're both in the same direction, then the

    current in the circuit increases, by a factor of

    (sum of the two battery voltages)

    divided by

    (voltage of the original battery alone).

    - - If the voltage of the two batteries is different AND you

    connect the new one so that they're in opposite directions,

    then the current in the circuit decreases, by a factor of

    (difference of the two battery voltages)

    divided by

    (voltage of the original battery alone)

    and the current flows in the direction of whichever battery has

    the greater voltage. If the new battery has greater voltage than

    the original one alone, then the current reverses, and flows in

    the opposite direction.

    I think that covers all the possibilities.
