Question

An alternating current is supplied to an electronic component with a warning that the voltage across it should never exceed 12 V. What is the highest rms voltage that can be supplied to this component while staying below the voltage limit in the warning?

    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
