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

i = 20 sin 80 pt + 20 sin 100 pt

i = 14.14 sin 40 t + 14.14 sin 50 t

i = 14.14 sin 80 pt + 14.14 sin 100 pt

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
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
Answer» D. i = 20 sin 80 pt + 20 sin 100 pt
