RL Parallel Circuit

In RL parallel circuit resistor and inductor are connected in parallel with each other and this combination is supplied by a voltage source , V in . The output voltage of circuit is V out . Since the resistor and inductor are connected in parallel, the input voltage is equal to output voltage but th

RL Circuit Transfer Function Time Constant RL Circuit as Filter

The resistor and inductor are the most fundamental linear (element having linear relationship between voltage and current ) and passive (which consume energy) elements. When resistor and inductor are connected across voltage supply, the circuit so obtained is called RL circuit . Types of RL Circuit

RL Series Circuit Analysis

What is an RL Circuit? An RL circuit (also known as an RL filter or RL network) is defined as an electrical circuit consisting of the passive circuit elements of a resistor (R) and an inductor (L) connected together, driven by a voltage source or current source . Due to the presence of a resistor in

Trees and Cotrees of an Electric Network

A tree of electric network is set of branches which is a set of branches which contains all the nodes of the network but does not form any closed path. It is similar to what a network topology is to a communications network. Let us explain the tree of electric network as defined above. The above fig

Cutset Matrix Concept of Electric Circuit

When we talk of cut set matrix in graph theory , we generally talk of fundamental cut-set matrix . A cut-set is a minimum set of branches of a connected graph such that when removed these branches from the graph, then the graph gets separated into 2 distinct parts called sub-graphs and the cut set m

What is Incidence Matrix?

Incidence matrix is that matrix which represents the graph such that with the help of that matrix we can draw a graph. This matrix can be denoted as [A C ] As in every matrix, there are also rows and columns in incidence matrix [A C ]. The rows of the matrix [A C ] represent the number of nodes and

H Parameters (Hybrid Parameters) in Two Port Networks

What are H Parameters (Hybrid Parameters?) Hybrid parameters (also known as h parameters ) are known as ‘hybrid’ parameters as they use Z parameters , Y parameters , voltage ratio, and current ratios to represent the relationship between voltage and current in a two port network . H parameters are u

Star To Delta Conversion Formula

Three branches in an electrical network can be connected in numbers of forms but most common among them is either star or delta form. In delta connection, three branches are so connected, that they form a closed loop. As these three branches are connected nose to tail, they form a triangular closed
