Determine the current through (2+j5) Ω impedance considering 50∠0⁰ voltage source.(a) 6.42∠77.47⁰(b) 6.42∠-77.47⁰(c) 5.42∠77.47⁰(d) 5.42∠-77.47⁰The question was asked during a job interview.I'm obligated to ask this question of Superposition Theorem in chapter Steady State AC Analysis of Network Theory |

Answer» RIGHT CHOICE is (d) 5.42∠-77.47⁰ The explanation is: According to the SUPERPOSITION theorem the current due to the 50∠0^o source is I1 with the current source 20∠30⁰ A short-circuited. I1 = (50∠0^o)/(2+j4+j5) = 5.42∠-77.47^o A. |
