Thevenin Equivalent Circuit

Thevenin Equivalent Circuit: In many practical applications, it is always not necessary to analyse the complete circuit; it requires that the voltage, current, or power in only one resistance of a circuit be found. The use of this theorem provides a simple, equivalent circuit which can be substituted for the original network. Thevenin Equivalent Circuit […]

Principle of Superposition Theorem

Principle of Superposition Theorem: The Principle of Superposition Theorem states that in any linear network containing two or more sources, the response in any element is equal to the algebraic sum of the responses caused by individual sources acting alone, while the other sources are non-operative; that is, while considering the effect of individual sources, […]

Star Delta Control Circuit

Star Delta Control Circuit: The star delta transformation is another technique useful in solving complex networks. Basically, any three circuit elements, i.e. resistive, inductive or capacitive, may be connected in two different ways. One way of connecting these elements is called the star connection, or the Y connection. The other way of connecting these elements […]

Source Transformation Technique

Source Transformation Technique: Source Transformation Technique – In solving networks to find solutions one may have to deal with energy sources. It has already been discussed before that basically, energy sources are either voltage sources or current sources. Sometimes it is necessary to convert a voltage source to a current source and vice-versa. Any practical […]

Nodal Analysis Examples

Nodal Analysis Examples: Nodal Analysis Examples – we discussed simple circuits containing only two nodes, including the reference node. In general, in a N node circuit, one of the nodes is chosen as reference or datum node, then it is possible to write N — 1 Nodal Analysis Examples by assuming N — 1 node […]
