    Answer:

    The highest rms voltage will be 8.485 V

    Explanation:

    For alternating electric current, rms (root means square) is equal to the value of the direct current that would produce the same average power dissipation in a resistive load

    If the peak or maximum voltage should not exceed 12 V, then from the relationship

    V_{rms} = \frac{V_{p} }{\sqrt{2} }

    where V_{rms} is the rms voltage

    V_{p} is the peak or maximum voltage

    substituting values into the equation, we’ll have

    V_{rms} = \frac{12}{\sqrt{2} } = 8.485 V
