    How were your Physics P-1 and P-3?

    My friends after exam, and while on the exam I knew it xD

    lol dont do this to us xD !!, now I'm getting scared O.O

    How were your Physics P-1 and P-3?

    I lost minimum 7 :( max may reach 16-20, but I did really good on paper 6 and 1 I guess, so still hoping for an A* :)

    P.D is the energy used to push th current, so if two current are pushing against each other, the one which has more volt will be able to push the other one (she mentiond 3 batteries, and one is reversed) so its 2:1, in small circuit i dont think there may be a large damage, so stronger current...

    wait!! current may flow, but the polarity may differ, and the reversed battery will be damaged. Now three DC batteries/Sources are connected in series,while the one is of reverse polarity of the 2 others ( that cause to establish two currents with opposite direction of each other). Under such a...

    A presence of a reversed will most likely prevent the current from flowing, and in most cases may damage the battery severely.
