Answer to Question #166134 in Electrical Engineering for Sankar

Question

If the currents in the three parallel branches of an ac circuit are given as I1 = 

2530A, I2 = 25e-jΠ/6A and I3 = (50 + j 50)A, express the total current in the form 

(i) I Φ and (ii) Im sin (ωt + Φ)

Answer 1

1) $I = 105.85 \text{\textless} 28.18^0$

2) $105.85 = (wt+118.18)$
