Single and Multi Mesh Analysis

The word mesh means a smallest loop which is closed one and formed by using circuit components. The mesh must not have any other loop inside it. Like the other network analysis procedures, we can use Mesh Analysis to find out the voltage , current or power through a particular element or elements. M

Voltage and Current Divider Rule

Current Division Rule When current flows through more than one parallel path, each of the paths shares a definite portion of the total current depending upon the impedance of that path. The definite portion of the total current shared by any of the parallel paths can easily be calculated if the impe

Nodal Analysis in Electric Circuits

Definition of Nodal Analysis Nodal analysis is a method that provides a general procedure for analyzing circuits using node voltages as the circuit variables. Nodal Analysis is also called the Node-Voltage Method . Some Features of Nodal Analysis are as Nodal Analysis is based on the application of

Source Transformation Technique

What is a Source Transformation? An electrical source transformation (or just ”source transformation”) is a method for simplifying circuits by replacing a voltage source with its equivalent current source, or a current source with its equivalent voltage source. Source transformations are implemented

Network Analysis or Circuit Analysis

Network Analysis is a process by which we can calculate different electrical parameters of a circuit element connected in an electrical network . An electrical circuit or network can be complicated too and in a complicated network, we have to apply different methods to simplify the network for deter

Essential Nodes And Essential Branches

What is an Essential Node? A node is defined as a point where two or more circuit elements are connected. An essential node is a particular type of node where three or more elements are connected. An essential node is a useful node to consider in circuit analysis. For example, in the below circuit,

Tellegen Theorem

This theorem has been introduced in the year of 1952 by Dutch Electrical Engineer Bernard D.H. Tellegen. This is a very useful theorem in network analysis. According to Tellegen theorem , the summation of instantaneous powers for the n number of branches in an electrical network is zero. Are you con

Maximum Power Transfer Theorem

Maximum Power Transfer Theorem Suppose we have a voltage source or battery that’s internal resistance is R i and a load resistance R L is connected across this battery. Maximum power transfer theorem determines the value of resistance R L for which, the maximum power will be transferred from source

Compensation Theorem

Concept of Compensation Theorem This theorem is based on one basic concept. According to Ohm’s law , when current flows through any resistor , there would be a voltage drop across the resistor. This dropped voltage opposes the source voltage. Hence voltage drop across a resistance in any network can

Reciprocity Theorem

What is Reciprocal Property? In many electrical networks it is found that if the positions of voltage source and ammeter are interchanged, the reading of ammeter remains the same. It is not clear to you. Let’s explain it in details. Suppose a voltage source is connected to a passive network and an a

Superposition Theorem

If there are several sources acting simultaneously in an electrical circuit, then the current through any branch of the circuit is summation of currents which would flow through the branch for each source keeping all other sources dead. Let us understand the statement. Here, two 1.5 Volt batteries p

Kirchhoff Current Law and Kirchhoff Voltage Law

There are some simple relationships between currents and voltages of different branches of an electrical circuit . These relationships are determined by some basic laws that are known as Kirchhoff laws or more specifically Kirchhoff Current and Voltage laws . These laws are very helpful in determini
