    Hello All

    For a 1.5V battery, what is the potential voltage at the positive
    terminal and negative terminal of battery?
    Is it 1.5 and 0 respectively?
    or 1.5 and -1.5?

    Hear from you all
    Thank you

    You probably have it right but are getting a bit bogged down :)
    The potential of the Pos terminal with respect to the Neg terminal is +1.5v.
    How you connect it is the key.

    Hi Jason,
    You are on solid ground.
    Voltage is a quantity used to measure difference in potential.
    Voltage on one point can only be expressed with respect to another point.
    The tip is +1.5 V wrt (with respect to) the bottom.
    The bottom is -1.5V wrt the top.
    If you put two cells in series aiding and made one reference point the
    middle where they touch, then the top would be +1.5v and the bottom would
    be -1.5v wrt the reference.
