    I have the following equation

    v= 6+40sin 1000∏t + 10sin(3000∏t +∏/4) + 3sin(5000∏t - ∏/12)

    I need to find the RMS voltage, current and frequency for a series circuit of 15Ω resister series with an inductor of 100mH and a 10nF capacitor.

    My problem is that i don't know how to find the time for the periodic frequency i know the the first harmonic is the 40 sin therefore is 40 volts and so on :)

    Kindly anyone can explain or give some help to me ?

    Thanks :D
