Q1:

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

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

ANS:C - i = 14.14 sin 80 pt + 14.14 sin 100 pt

Peak value = 14.14 A; ω1 = 2p x 40, ω2 = 2p x 50
