Test: Circuit Theorems- 2 - Electrical Engineering (EE) MCQ

The v-i characteristic of an element is shown in figure below. The element is

If the source impedance is inductive, for maximum transfer of power from the source to the load, the load should be

The equivalent resistance between terminal A and B for the given circuit is
​

Assertion (A): Norton’s theorem is called dual of the Thevenin’s theorem.
Reason (R): If the Thevenin’s equivalent voltage source is converted to an equivalent current source, the Norton’s equivalent is obtained.

Assertion (A): In any active network, maximum power transfer to the load takes place when the load impedance is equal to an equivalent impedance of the network as viewed from the terminals of the load.
Reason (R): For finding the maximum power transfer to the load, any network has to be first converted into Th even in’s equivalent across the terminals of the load.

Assertion (A): The substitution theorem is very useful in the networks consisting the mutual inductances.
Reason (R): By the substitution theorem, the effect of mutual inductances may be replaced by equivalent dependent sources of the same Value.

Consider the following statements related to
Thevenin’s theorem:
For the application of Thevenin’s theorem
1. the circuit should not. contain non-iinear elements.
2. the circuit may contain unilateral or bilateral elements or both.
3. there should not be magnetic coupling between the load and circuit, to be replaced by Thevenin's theorem.
4. there should not be controlled sources on the load size, controlled from some other oart of the circuit.
