Norton’s Theorem
Norton’s Theorem states that – A linear active network consisting of independent or dependent voltage source and current sources and the various circuit elements can be substituted by an equivalent circuit…
Thevenin’s Theorem
Theory: In electrical circuit theory, Thevenin’s theorem for linear electrical networks states that any combination of voltage sources, current sources and resistors with two terminals is electrically equivalent…
Mesh Analysis
In Mesh analysis, we will consider the currents flowing through each mesh. Hence, Mesh analysis is also called as Mesh-current method. A branch is a path that joins two nodes and it contains…
Nodal Analysis
There are two basic methods that are used for solving any electrical network: Nodal analysis and Mesh analysis. In this chapter, let us discuss about the Nodal analysis method. In Nodal analysis, we will consider…
Steady State Solution of DC Circuits
Resistance in series connection: The resistors R1, R2, R3 are connected in series across the supply voltage “V”. The total current flowing through the circuit is denoted as “I”. The voltage…
Dependent And Independent Sources
Electric circuit: An electric circuit is a closed path comprising of electrons flowing along it from a voltage source or a current source. Important points: 1.Source-The point where the electrons enter an…
What is a capacitor?
A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store energy electrostatically in an electric field. The forms of practical capacitors vary widely, but all contain at least two electrical conductors (plates) separated by a dielectric (i.e., insulator). The conductors…
What is an Inductor?
Inductors, Coils and Chokes An inductor is a passive electrical component that opposes sudden changes in current. Inductors are also known as coils or chokes. The electrical symbol for an…
INSTANTANEOUS POWER
Power is the most important quantity in electric utilities, electronics . . . because such system involve transmission of power from one point to another.Instantaneous power is the power at any instant…
Kirchhoff’s laws of electric circuits
Two simple relationships can be used to determine the value of currents in circuits. They are useful even in rather complex situations such as circuits with multiple loops. The first relationship deals with…
