## Norton’s Theorem Explained with Example

Norton’s Theorem states that any linear bilateral circuit consisting of independent and or dependent sources viz. voltage and or current sources can be replaced by an equivalent circuit consisting of a current source in parallel with a resistance. The current source is the short circuit current across the load terminals and the resistance is the … Read more

## Substitution Theorem Explained with Diagram

Statement of Substitution Theorem: Substitution Theorem states that any branch of a DC bilateral circuit can be substituted by a combination of various circuit elements, provided the current & voltage across the branch remains unchanged. Basically, this theorem tells us the boundary condition to replace a circuit branch. If the value of current and voltage … Read more

## What is Reciprocity Theorem?

Reciprocity Theorem states that, the value of current due to a single source in any particular branch of circuit is equal to the value of current in the original branch where the source was placed when the source is shifted to that particular branch of circuit. This theorem is only applicable for a reciprocal network … Read more

## Superposition Theorem Explanation

Superposition theorem states that the resultant current in any branch in a liner network having a number of sources, is the algebraic sum of the current that would be produced in it, when each source acts alone replacing all other independent sources by their internal resistance. This theorem is very useful for solving a network … Read more

## Maximum Power Transfer Theorem

Maximum Power Transfer Theorem states that, for any type of circuit whether ac or dc, maximum amount of power is delivered from source to load when the source impedance as viewed from the load terminal is equal to the load impedance. This theorem is used to find the value of load impedance for which there … Read more

## Dependent Current Source Explained

Dependent Current Source is a four terminal active circuit element whose output current is dependent on circuit current or voltage. An active circuit element is one which can deliver power to the circuit. In this article, we will discuss the concept of dependent current source in detail with the help of circuit diagram. A current … Read more

## What is Dependent Voltage Source?

Dependent Voltage Source is a four terminal source whose output voltage is dependent on circuit current or voltage. Unlike ideal voltage source, the magnitude of voltage output of this source is not constant. Rather, it is linearly related to input current or voltage. In fact, the output voltage of dependent voltage source is a scalar … Read more

## Source Transformation Explained with Examples

Source Transformation is a technique to convert one kind of source into other. There are two types of sources: Voltage source and Current Source. Therefore, this technique will convert voltage source into equivalent current source and current source into equivalent voltage source. This kind of transformation is required to solve circuit network. Here, the sources … Read more

## Ideal Current Source & Practical Current Source Explained

Ideal Current Source: Definition: An ideal current source is a two terminal device which supplies constant current irrespective of load resistance. The value of current will be constant with respect to time and load resistance. This means that the power delivering capability is infinite for this source. An ideal current source has infinite parallel resistance … Read more
