Determine the Thevenin’s voltage across ‘ab’ terminals in the circuit shown below.(a) 41.86∠0⁰(b) 42.86∠0⁰(c) 43.86∠0⁰(d) 44.86∠0⁰The question was asked in an internship interview.My enquiry is from Thevenin’s Theorem in section Steady State AC Analysis of Network Theory

Answer»

The correct CHOICE is (B) 42.86∠0⁰

Best explanation: The VOLTAGE ACROSS the points a and b is called thevenin’s equivalent voltage. Thevenin’s equivalent voltage Vab=100∠0^o×j3/(j3+j4) = 42.86∠0^o V.
