Voltage with a sine function.

  1. Sep 6, 2006 #1
    In an electrical outlet, the voltage, V, in volts, is given as a function of time, t, in seconds, by the formula

    V = V0sin(120pit)

    What does V0 represent in terms of voltage?

    Well, V0 is the amplitude, but I don't know what it represents in terms of voltage... I guess i'm just having trouble wording it.

    Should it be "V0 represents the maximum voltage"?

    This is a physics question in a math forum, but yes to answer your question. In general, the position of the "Vo" term is the amplitude, which in this case is the maximum value of the voltage.
