AC generators and transformers

Alternating Current can be defined as the flow of charge wherein the charge is said to be changing its position periodically, thus resulting in the reversing of the voltage levels with the current. AC is used over DC in our houses and official buildings because it is less hazardous and can be easily transferred within […]

A transformer is a device that increases or decreases voltage in its most basic form. For example, the output voltage of a step-up transformer is increased, whereas the output voltage of a step-down transformer is dropped. As a result, the output current of the step-up transformer will be reduced, while the output current of the

The general definition of alternating current is that it is a type of electric current in which, at regular and random intervals, the direction of flow of electrons changes back and forth. This means that the polarities of the current keep on changing with time. In other words, we can say that the current changes

Reactance Properties Reactance is the opposition exhibited to the movement of alternating current in an inductor or capacitor due to inductance or capacitance. Reactance is like an alternating current equivalent of direct current resistance. Resistance stores and disperses energy as heat when there is reactance to the movement of alternating current in an inductor, capacitor

An AC generator is a device that converts mechanical energy to electrical energy. The input supply of an AC generator is mechanical energy. This is supplied by combustion engines, gas turbines, and steam turbines. The output energy is alternating electrical power. It is in the form of alternating voltage and current. Two Types Of AC

Introduction Alternating current (AC) is the flow of electric charge whose magnitude changes continuously with time and its direction reverses periodically. Most of the electric power generated and used worldwide is in the form of alternating current. In most electric circuits, the waveform of AC is a sine wave, whose positive half corresponds with the

Alternating current (AC) is an electric current that flows in both directions at regular intervals. It begins from zero, reaches its peak, decreases to zero, changes its direction, and repeats the whole cycle infinitely. The interval of time between the completion of a precise value of two successive cycles is known as a period. The

The main purpose of an electric generator is to metamorphose mechanical energy into electrical energy. This makes it possible for transmission over large distances through power lines. There are predominantly two types of generators. They are Direct Current (DC) generators and Alternating Current (AC) generators. Alternating Current is abbreviated as AC. AC generators are also

Eddy currents are produced due to changes in the magnetic field. In other words, we can say that when the magnetic flux is flowing inside a coil, these currents are formed. These currents are created following the concept of electromagnetic induction. They are always present in closed loops. This is the nature of all metals. 

In electrical engineering, a halfwave rectifier is a type of rectifier that allows only one-half cycle of an alternating current voltage waveform to pass while blocking the other half cycle. When building a half-wave rectifier circuit, only one diode is required, making it the simplest type of rectifier circuit to construct. In a halfwave rectifier
