Watts = E*I, or in this case 68 watts
    Ohms law doesnt add up with alternating current. Not your basic triangle chart anyways lot of other factors peak voltage ect.

    It does for resistive loads the CCH is resistive.

    You are right that it will not work with capacitive or inductive loads.

    Yea your right i just tested this with my oven😊 worked like a charm. I do remember messing with this in school with light bulbs and it wouldnt add up. I believe we came to the conclusion bulbs did not actually pull the wats they were rated for. Thanks for the correction

    Incandescent bulbs are also resistive loads. They are heaters.

    Hey I'm at 41 years and the only thing I know for sure is the more I learn the more there is to learn.

    In the field there are many things like instrument error that can make not add up.



    Keep going after it.
