    • The Kelvin Scale

      The Kelvin Scale

      The Kelvin Scale is a thermometric scale used in physical science to describe the absolute temperature of an object, substance, or area. While Fahrenheit and Celsius scales measure temperature, the Kelvin Scale defines temperatures relative to an object’s thermodynamic movement. As a result, the Kelvin Scale does not use degrees, but simply a number followed

    • What is a Peltier Cooler?

      What is a Peltier Cooler?

      A Peltier Cooler or Peltier Heat Pump is a type of refrigerator that has no moving parts and is capable of transferring heat to either side of itself. Peltier Coolers are advantageous as they are solid state devices and only require a DC electrical current in order to cool an object or area. A Peltier

    • What is a Pitot Tube?

      What is a Pitot Tube?

      A pitot tube measures pressure levels in liquids. They are most commonly seen in laboratory settings but can be seen in industrial applications as small cylinders. While a pitot tube is not the only device that measures fluid pressure, it is capable of being implemented in much more diverse environments than similar devices. How Pitot

    • What is Magnetic Wire?

      What is Magnetic Wire?

      Magnetic wire is a copper or aluminum wire that produces an electromagnetic field when wrapped into a coil and connected to a power supply. It is used in a number of applications and is a vital component in many different devices. Magnetic wire can be used in electrical to electrical, electrical to mechanical, and mechanical

    • How Do X-Ray Machines Work?

      How Do X-Ray Machines Work?

      The Parts of an X-Ray Machine There are three main parts of an x-ray machine. The first is the x-ray tube. This is responsible for the creation of x-rays. Therefore, without this functioning properly, there would be little chance for the x-ray to work in the right way. It generates enough x-rays so that when

    • What is Microfarad?

      What is Microfarad?

      The term microfarad is used to describe a unit of capacitance that is 0.000001 farad. The symbol that represents a microfarad is µF. It is commonly used in utility alternating-current and audio frequency circuits. The capacitors that are found in them normally have a rating of 1 µF or more. However, even smaller capacitors are

    • Electroluminescent Wire

      Electroluminescent Wire

      Electroluminescent wire (EL wire) is a thin wire that produces 360 degrees of visible light. EL wire differs from string lights, such as Christmas lights, which only produce light at specific points. It uses a phenomenon known as electroluminescence to generate light when electricity runs through it. EL wire is very thin and flexible and

    • Vibration Isolators

      Vibration Isolators

      There are a number of vibration sources throughout the world. In most cases, these movements have undesirable effects on things used in daily life, such as buildings and vehicles. Vibration isolators reduce or eliminate the effects of vibrations on equipment and structures. These devices are commonly referred to as shock mounts, snubbers, machine mounts, and

    • Antigravity Propulsion

      Antigravity Propulsion

      True antigravity propulsion involves using a material or technological effect that counteracts the effects of gravity without using aerodynamic lift, electromagnetism, or some other balancing force. Likewise, antigravity does not refer to situations in which an object or person experiences lack of weight such as being in a pool, free fall, or high altitude orbit.

    • What is Luminous Flux?

      What is Luminous Flux?

      Luminous flux (luminous power) is the measurement of the (perceived) power of light. It is adjusted to take the human eye’s sensitivity to the different wavelengths of light into account. Luminous flux differs from radiant flux in this manner, since radiant flux is a measurement of the total power of light emitted independent of wavelength.
