Maximum Power Transfer Theorem

Maximum Power Transfer Theorem: Here, the maximum power transfer theorem has been discussed for resistive loads. The maximum power transfer theorem states that the maximum power is delivered from a source to its load when the load resistance is equal to the source resistance. It is for this reason that the ability to obtain impedance …

Norton Equivalent Circuit

Norton Equivalent Circuit: Another method of analysing a complex impedance circuit is given by Norton’s theorem. The Norton Equivalent Circuit form of any complex impedance circuit consists of an equivalent current source IN and an equivalent impedance ZN, arranged as shown in Fig. 7.24. The values of equivalent current and impedance depend on the values in …

Thevenin Equivalent Circuit

Thevenin Equivalent Circuit: Thevenin’s theorem gives us a method for simplifying a given circuit. The Thevenin Equivalent Circuit form of any complex impedance circuit consists of an equivalent voltage source VTh, and an equivalent impedance ZTh, arranged as shown in Fig. 7.19. The values of equivalent voltage and impedance depend on the values in the …

Superposition Theorem Formula

Superposition Theorem Formula: The Superposition Theorem Formula also can be used to analyses ac circuits containing more than one source. The superposition theorem states that the response in any element in a circuit is the vector sum of the responses that can be expected to flow if each source acts independently of other sources. As …

Node Voltage Method

Node Voltage Method: The node voltage method can also be used with networks containing complex impedances and excited by sinusoidal voltage sources. In general, in an N node network, we can choose any node as the reference or datum node In many circuits, this reference is most conveniently chosen as the common terminal or ground …

Mesh Current Equation

Mesh Current Equation: We have earlier discussed meth analysis but have applied it only to resistive circuits. Some of the ac circuits presented in this chapter can also be solved by using Mesh Current Equation analysis. We already know, the two basic techniques for writing network equations for mesh analysis and node analysis were presented. …
