Alternating currents and voltages are sinusoidal and vary with time alternating currents produce different responses in resistors, capacitors, and inductors th. Alternating current when the movement of electrons is caused by a magnet traveling inside a coil of metal wire, it's said to be of electromagnetic origin actually, the electrons move back and forth between the atoms, as the magnet alternately pushes and pulls them this type of current is called alternating current. The current, which reverses its direction periodically in second , is called “ alternating current”the polarity of the voltage , is reversed periodically in an alternating current source so the current reverses its direction periodically hence the name alternating current (ac) indicating current is alternating. This article discusses what is a transformer, construction of transformer, working principle, basic theory & why transformers works with alternating current.
Where did the australian rock band ac/dc get their name from why, alternating current and direct current, of course both ac and dc describe types of current flow in a circuit in direct current (dc), the electric charge (current) only flows in one direction electric charge in alternating current (ac), on the other hand,. Certain sources of electricity (most notably, rotary electro-mechanical generators) naturally produce voltages alternating in polarity, reversing positive and negative over time either as a voltage switching polarity or as a current switching direction back and forth, this “kind” of electricity is known as alternating current (ac). What's the difference between alternating current and direct current electricity flows in two ways: either in an alternating current (ac) or in a direct current (dc) electricity or 'current' is nothing but the movement of electrons through a conductor, like a wire the difference between ac and dc lies in the direction in. Alternating current (ac) is the current generated by the vast majority of power plants and used by most power distribution systems, as it is cheaper to generate and has fewer energy losses than direct current when transmitting electricity over long distances although for very long distances, direct current can often be better.

An electric current that reverses its direction of flow at regular intervals because the voltage of alternating current can be easily controlled with transformers, this is the type of electricity generated by power stations the transformers raise the voltage to make it easier to transmit over long distances, then lower the voltage for. The alternating current generator an electric generator, or dynamo, is a device which converts mechanical energy into electrical energy the simplest practical generator consists of a rectangular coil rotating in a uniform magnetic field the magnetic field is usually supplied by a permanent magnet this setup is illustrated.
An electric current in which the direction of flow of the electrons reverses periodically by a sinusoidal law, hence having an average of zero, with positive and negative values (with a frequency of 50 hz in europe, 60 hz in the us, 400 hz for airport lighting, and some others) especially such a current produced by a rotating. Note: this section and others concerned with alternating current require an understanding of sine and cosine mathematical functions, resembling the outlines of waves they are discussed in the sections on trigonometry, starting with (m-7) trigonometry---what is it good for, though the continuous sine wave is only. Alternating current (ac) is easy to generate and use, with numerous advantages over direct current in this lesson, we'll define ac, discuss its.
By doug lowe an electric current that flows continuously in a single direction is called a direct current, or dc the electrons in a wire carrying direct current move slowly, but eventually they travel from one end of the wire to the other because they keep plodding along in the same direction the voltage in a direct-current.
Alternating current (ac) is an electric current that reverses direction cyclically – unlike direct current (dc), which always travels the same way, as is the case with anything powered by a battery, for example ac is the current running through the electric wires and appliances in your home the magnitude of. Alternating current (ac) electricity is the type of electricity commonly used in homes and businesses throughout the world while direct current (dc) electricity flows in one direction through a wire, ac electricity alternates its direction in a back-and-forth motion the direction alternates between 50 and 60. Get the full course at: in this lesson, we will discuss what alternating current (ac) is and how it differs from dc current in a.
