  1. Two current sources each of rms value 10 A have frequencies 40 Hz and 50 Hz respectively. They are connected in series, the expression for resultant wave is

    2. A.
    i = 10 sin 40 t + 10 sin 50 t
    B.
    i = 14.14 sin 40 t + 14.14 sin 50 t
    C.
    i = 14.14 sin 80 pt + 14.14 sin 100 pt
    D.
    i = 20 sin 80 pt + 20 sin 100 pt
