    Quick answer the current will go down.

    The formula is

    E = I * R. The variation is a direct one. Let us suppose E = 12 volts.

    12 = I * 3 ohms Divide both sides by 3

    12/3 = I

    I = 4 amps

    Now do it again for 6 ohms

    12 = I * 6 Divide both sides by 6

    12/6 = I

    I = 2

    So the current went down from 4 to 2
