Find the thevenin’s impedance in the circuit shown below.(a) 4.83∠-1.13⁰(b) 5.83∠1.13⁰(c) 4.83∠1.13⁰(d) 5.83∠-1.13⁰I have been asked this question in my homework.My question is based upon Thevenin’s Theorem in portion Steady State AC Analysis of Network Theory

Answer»

Correct choice is (a) 4.83∠-1.13⁰

Easiest EXPLANATION: The impedance is equal to the impedance SEEN into the network across the OUTPUT TERMINALS. ZTH = (j5-j4)+(3-j4)(4+j6)/(3-j4+4+j6) = 4.83∠-1.13⁰Ω.
