Advantages and disadvantages of electro

Published on October 27th, by Md Mehedi 58 Advantages and Disadvantages of Electronic Communication Technology in Modern Communication Communication is needed for decision making, coordination, control, and planning. Worldwide communication has been facilitated by the electronic transmission of data which connects individuals, regardless of geographic location, almost instantly. Due to electronic technology, jobs, working locations and cultures are changing and therefore people can easily access worldwide communication without any physical movement. It requires only a few seconds to communicate through electronic media because it supports quick transmission.

Electroless Nickel - Pretreatment

By David Sandoval; Updated April 23, In a typical day, an average person may use electrical power hundreds of times without giving it a second thought. For many people, flicking a switch to turn on a light or plugging an electrical device into a wall socket is second nature.

Much of that electricity is supplied by electromechanical devices, such as the electrical generators used by hydroelectric power plants or wind turbines.

Electrical power can also be generated by chemical or photoelectric means, such as by using batteries or solar energy. Depending upon the type of electrical power needed, one or more methods of electric power generation may be used simultaneously. Unless some part of the generation process is inefficient or harmful in some way, it can be advantageous to use such a device to generate electrical power.

One example of this is an alternating-current AC generator. When rotational mechanical energy turns a coil inside of the generator, it exposes that coil to changes in magnetic field.

Those changes induce the production of alternating current voltage — voltage where the current changes directions with a certain frequency — between the two output ends of the coil.

Since no other energy is required other than the mechanical motion of the rotating coil, this type of device can be advantageous in situations where there is a ready source of mechanical energy, such as a steam or gas turbine, or a diesel or gasoline engine.

Another advantage of using an electromagnetic energy source is that you can generate either AC or direct-current DC electrical power. As noted before, an AC generator uses changing magnetic fields to create AC electrical power.

A DC generator operates in a similar fashion; however, it requires a few extra pieces to convert AC electrical power to DC. Many DC motors and generators use a device called a commutator to convert the alternating current that comes out of the power generator into current that flows in only one direction, or direct current.

As with an AC generator, many types of DC generators only require a reliable source of mechanical energy to generate electricity. Sciencing Video Vault Disadvantages Electromagnetic power sources may not be as useful, or can perhaps be dangerous to use, under certain circumstances.

For instance, if you need to have a power source that must have a regulated current output, both AC and DC power generators would need to be run at a non-varying speed.

Further, while a DC power generator produces electrical current that flows in one direction, the electrical current is irregular. To regulate the current produced by a DC generator, you would need additional electrical equipment, such as a battery, a capacitor and an inductor, as well as electronic components called diodes to ensure that the current stays within a regulated range.

Since generators use electromagnetic fields to produce electricity, these fields can be dangerous to some people who use sensitive medical equipment, such as pacemakers.

These same electromagnetic fields can also interfere with other electrical and electronic devices, such as cell phones and computers. The electrical energy generation process also produces heat; therefore, it would be best not to use a generator around items or in environments where there is flammable or combustible material.

Electroless nickel plating (EN) is an auto-catalytic reaction that deposits an even layer of nickel-phosphorus or nickel-boron alloy on the surface of a solid material, or substrate, like metal or process involves dipping the substrate in a bath of plating solution, where a reducing agent, like hydrated sodium hypophosphite (NaPO 2 H 2 · H 2 O), reacts with the material's ions to.
