      How a Laser Printer Works

      A laser printer unlike an inkjet printer uses a laser light beam for printing operations. It is also distinct from other printers because of its exceptional printing speed as well as highly accurate rendering. It utilizes a xerographic (a process of creating an image by the action of light on a specifically coated charged plate)

    • What is a Generator?

      What is a Generator?

      A generator (electrical) is a device that converts mechanical or chemical energy into electrical energy. Generators often use motors, turbines, engines, cranks, pistons, or other sources of mechanical energy. Likewise, generators may use chemicals or other materials that produce electricity when mixed or ignited. Generators do not produce electricity itself, but simply produce a flow

    • Who Invented Electricity?

      Who Invented Electricity?

      No one person invented electricity, but its modern day use is the result of the work of inventors, scientists, and researchers who toiled over the subject for millennia. In order to fully understand electricity in our modern world, one has to first understand the pioneers who date back to as early as the ancient Greeks,

    • How a Fuel Cell Works

      A fuel cell is a device that produces electrical energy through chemical reaction. This energy conversion process is known as electro-chemical energy conversion. The simplest form of electrochemical device that we use in our day to day life is a battery cell. A fuel cell is different from a battery cell in so far as

    • How OnStar Works

      How OnStar Works

      OnStar was developed and deployed by General Motors for the purpose of providing fast and effective response in the event of vehicular accidents. OnStar has now been improved to provide more than the basic services. Now, it provides assistance with directions, car breakdown help as well as communications and leisure services. OnStar is a system

    • How Do Electric Motors Work?

      How Do Electric Motors Work?

      As society is trying to slowly ween itself off of oil-dependency, the search for alternative fuels continues. One source of alternative "fuel" that already exists, however, is the electric motor. Electric motors are commonly found in vehicles, toys, and other electronic devices but there is still a campaign to improve the quality and efficiency of

    • Isobutane


      Isomers are compounds with the same molecular, but different structural formulas. Isobutane is an isomer of butane. It belongs to a class of compounds called alkanes, which are chains of carbon atoms where each carbon atom is attached to as many hydrogen atoms as possible.  Its chemical formula is C4H10. Butane consists of four carbon

    • How Do Neurons Communicate?

      How Do Neurons Communicate?

      Neurons communicate by sending electrical signals throughout the body. The exact process is an electrochemical one and the speed in which neurons communicate is so fast that seeing someone drop out of someone's hand and trying to grab for it–a process that requires the image to get into the brain, processed and then a signal

    • Eddy Currents

      Eddy Currents

      Eddy currents are also referred to as Foucault currents and are created when conductors are exposed to a changing magnetic field because of a field source’s relative motion. Their applications include induction heating and non-destructive testing. Eddy currents are continually researched in order to develop new applications. How do Eddy Currents Work? Eddy currents are

    • Hybrid Cars

      Hybrid Cars

      Most hybrid cars use a combination of gasoline and electric engines. There are also types of hybrid cars that use a combination of diesel and electric engines. Gasoline & Electric -Powered Cars ‘Regular’ gasoline-powered cars derive their propulsion power from combustion of gasoline. The combustion of gas produces the energy needed to turn the transmission
