    Answer:

    Current in the hair dryer will be equal to 15 A

    Explanation:

    We have given that household is operated at 110 volt

    So potential difference V =110 volt

    Power drawn by hairdryer is P = 1650 watt

    We have to find the current in the hair dryer

    We know that power is given as P = VI, here V is potential difference and I is current

    So 1650=110\times I

    I = 15 A

    So current in the hair dryer will be equal to 15 A
