    If i put two batteries in parallel one battery 10v and the other 5v how do i calculate the resulting voltage when they are in parallel ?

    If you do that, ur 5V will start to charge, and even if the 5V one is rechargeable, it will probably blow up in ur face.
    So basically u won't need to worry about voltage measurements.

    You must not connect batteries of different voltages in parallel, as you risk melting wires, fire, and explosion.

    When I was a small child, I think that so but never tried. :D So now, I asked it for confirming. :)

    If you run 2 batteries or v sources, like a solar panel & backup battery, provide each with a blocking diode[ OR GATE]. Running 2 12 V batteries in parallel is common in RVs, but preffer 2 6s in series.
