In the power bus of Fig. 1.2, determine the \(i_{3}(t)\) if we know that \(i_{1}(t)=10 \cos (10 t) A, i_{2}(t)=10 \sin (10 t) A\), and \(i_{4}(t)=10 \sqrt{2} \cos \left(10 t+45^{\circ}ight) A\).

1) \(10 \sqrt{2} \mathrm{~A}\)

2) \(\left(5 /-45^{\circ}ight) A\)

3) \(\left(10 / 45^{\circ}ight) A\)

4) \(0 \mathrm{~A}\)
