    Answer: 2.0 ohms

    Explanation:

    Given that,

    Voltage (V) = 12V

    current (I) = 6A

    resistance (R) = ?

    Since, voltage, resistance and current are involved, apply the formula for ohms law:

    V = I x R

    Make R the subject formula

    R = V / I

    R = 12V / 6A

    R = 2.0 ohms

    Thus, the resistance will be 2.0 ohms.
