    Can someone help me on the solutions for the following problems ?.
    1) Find the average power delivered to the series combination of 5ohm resistor and 10mH inductor by the voltage a)20cos1000t - 15sin1000t b)20cos1000t - 15sin500t
    c)20cos1000t - 15sin(1000t - 36.9(degree)) volt.

    2) Find effective value of a)2cos(1000t+0.1*pi) - sin(1000t - 0.15*pi) volt b) 2cos1000t +sin(500t+0.2*pi) volt.
    I want to have a clear idea on ,
    1 ) finding the average
    and
    2 ) RMS values of series combination of sine waves with same and different frequencies and phase.

    This sounds like homework to me, hence moved from General Electronics Chat to Homework Help.
