Series and Parallel Connection of Coupled Coils

There are four possible ways of connecting coil in series and parallel. We will analyze each case one by one.

INTRODUCTION Whenever current flows through a conductor whether as ac or dc, a magnetic field is generated about that conductor.

INTRODUCTION A pair of terminals through which a current may enter or leave a network is known as a port.

A network is in resonance (or resonant) when the voltage and current at the network input terminsl are in phase.

TRANSIENT ANALYSIS Analysis of Different Circuits Source Free Parallel RLC Circuit

In many practical situations, a circuit is designed to provide power to a load. There are applications in areas such

Norton theorem bears a close resemblance to Thevenin’s theorem. The Norton equivalent of a linear network is the Norton current

To develop Thevenin’s theorem, consider figure consisting of two two-terminal networks, N and NL, joined at A and B. ‘N’

INTRODUCTION In the practical analysis of electric networks, engineers often need to know the power absorbed by one particular load.

It is inevitable to ask that which of the method is better? This can be decided over two factors discussed

Mesh analysis provides another general procedure for analyzing circuits, using mesh currents as the circuit variables. Recall that a loop

INTRODUCTION Having understood the fundamental laws of circuit theory (Ohm’s law and Kirchhoff’s law), we are now prepared to apply

A typical magnetic circuit with an air-gap is shown below in the figure. It is assumed that the air-gap is

MAGNETIC CIRCUITS The complete closed path followed by the lines of flux is called a magnetic circuit. In low power

The source of the steady magnetic field may be a permanent magnet, an electric field changing linearly with time, or

Experiment has shown that a force exists between any two bodies that have a net electric charge, that is an

The total outward electric flux ψ through any closed surface is equal to the total charge enclosed by the surface.
