Circuit Theorems in AC Analysis Online Test – Multiple Choice Questions and Answers 1. In order to get maximum power transfer from a capacitive source, the load must be as capacitive as it is inductive have a capacitive reactance equal to circuit resistance have an impedance that is the complex conjugate of the source impedance none of these 2. The Thevenin equivalent voltage is the open circuit voltage equal to the source voltage the same as the load voltage none of these 3. The Norton equivalent current is the current through the load the open-current from the source the short circuit current none of these 4. In applying the superposition theorem, the sources are considered one at a time with all others replaced by their internal impedance all sources are considered independently the sources are considered one at a time with all others replaced by their internal resistance all sources are considered simultaneously 5. The two basic components of a Thevenin equivalent ac circuit are the equivalent voltage source and the equivalent series resistance the equivalent voltage source and the equivalent series impedance the equivalent voltage source and the equivalent parallel impedance the equivalent voltage source and the equivalent parallel resistance 6. Norton’s theorem gives an equivalent current source in series with an equivalent impedance an equivalent voltage source in parallel with an equivalent impedance an equivalent voltage source in series with an equivalent impedance an equivalent current source in parallel with an equivalent impedance 7. If two currents are in the same direction at any instant of time in a given branch of a circuit, the net current at that instant is zero is the sum of the two currents cannot be determined is the difference between the two currents Loading … Question 1 of 7
