Sinusoidal steady-State proplem

  1. Nov 7, 2004 #1
    hi everyone

    I have a hard time to figure out these proplems in the picture.

    Here are my solutions:

    1) V1 = V*R/(R+ L) (voltage divider)
    but we have V = cos(wt)
    => V1 = cos(wt)*R/(R+L)

    2) L* di/dt + R*I = V1*cos( w*t + [​IMG] )
    ==> V1 = (L*di/dt + R*I)/cos(w*t +[​IMG])

    3) ?

    4) V2 = R/(R +C)

    5)?

    6)?

    7) ?
