When setting up an electrical assembly and attempting to organize wires, terminal blocks are useful devices to implement more optimal and efficient connections. Terminal blocks are simply modular, insulated blocks that secure two or more wires in an assembly, bolstering organization while protecting wires from damage. With several individual terminals arranged in a strip, terminal blocks open up more opportunities to connect wiring to a ground, connect electrical switches and outlets to mains, and more. As terminal blocks can work with multiple types of connector components while deterring corrosion, damage, and other issues, it can be quite useful to have a general understanding of common variations and options.

Generators and alternators are both common systems used to generate electrical current, but while a generator is able to produce direct current (DC) voltage, an alternator supplies alternating current (AC) voltage. Although AC voltage can be useful for a number of applications, it cannot be used for devices such as batteries that are commonly found in automobiles and aircraft alike. Despite this, alternators are a very common feature in such vehicles, providing the power necessary to charge batteries and power electrical systems. Since AC voltage cannot be used in these instances, devices known as rectifier diodes must be in place for the means of transforming AC voltage into DC voltage.

Diodes are a staple of digital electronic circuits, serving to direct current in a single direction. This is done through a low resistance being implemented in one direction, while a high resistance deters flow in the other. In a forward bias diode, the polarity of the external voltage will oppose the built-in potential, causing current to flow through the p-n junction. However, some diodes will have an external voltage that is of the same polarity as the built-in potential, blocking the flow of current as per the reverse bias phenomenon. There are various types of diodes available on the market, each varying in their characteristics of voltage and current to accommodate different applications. Varactor diodes in particular are types that are known for their ability to take on the application of reverse voltages. As a diode type commonly found in various FR filters, parametric amplification circuits, and other assemblies, it can be beneficial to have a better understanding of its design.

Resistors are commonplace components for countless electronic components, coming in the form of passive components that impede the flow of current within electrical circuits. Resistors can come in numerous forms, many featuring varying designs and characteristics that allow them to take on differing roles. Depending on the resistor, one may use such components for dividing voltages, generating heat, controlling gain, terminating transmission lines, and much more. To familiarize yourself with resistors, we will provide a brief overview of the most common types.

The first commercial air passenger flight occurred in 1914. It was a mere 23 minute journey from St. Petersburg, Florida to the neighboring city of Tampa. Since this flight, the commercial aviation industry has taken huge leaps in terms of technology and safety, in addition to its financial boom. Today, aviation is one of the safest modes of transportation. Despite this, many people are weary of flying during inclement weather, especially a lightning storm. However, aircraft are designed to be prepared for conditions like this. In this blog, we will discuss how aircraft are prepared for a lightning strike, how they are protected, and how they prevent damage.

The new normal is a phrase that has cropped up numerous times this year and in the current COVID 19 climate, it’s no surprise to anyone. The new normal is a phrase that describes a world with a new set of commonalities. Masks is the best example of this, but so are things like ventilators and respirators. These words are being used several times a day in teh news and in some sectors, every language. If you’re not familiar with what a ventilator or a respirator are, read on below. In this article we will discuss the two and describe their similarities and their differences.

Pressure transducer, pressure transmitter, and pressure sensor are often used interchangeably. This is not entirely correct. First, let’s look at the differences between pressure transducers and transmitters. In its most basic form, a transducer is a device used to measure pressure, load, force, or other factors, and convert the reading into an electronic signal. A transmitter also converts a reading into an electrical signal, but subsequently amplifies, modifies, and sends the signal to another receiver.

A temperature sensor is a device used to measure temperature through an electrical signal that requires a thermocouple. This electronic device consists of two dissimilar conductors (different types of metals) joined together at one end, which form electrical junctions at varying temperatures. When the junction of the conductors is heated or cooled, it emits a temperature dependent voltage formed by a thermoelectric effect, which can be used to measure temperature.
