    There would be no change in current.

    The easiest way for me to demonstrate it is like this:

    Ohm’s law: I = V / R

    Original current = (original voltage) / (original resistance)

    New current = (0.5 x original voltage) / (0.5 x original resistance)

    Cancel 0.5 out of numerator and denominator:

    New current = (original voltage) / (original resistance)

    So New current = Original current
