A variable resistor is a resistor with a resistance value that can be adjusted. Essentially, variable resistors are electromechanical transducers that normally work by sliding a contact over a resistive element. When a variable resistor is used as a potential divider by using three terminals, it is called a potentiometer. When only two terminals are used, it is known as a rheostat and functions as a variable resistance. There are also electronically controlled variable resistors, which can be controlled electronically instead of by mechanical action. In these cases, the resistor is called a digital potentiometer. In this blog, we will discuss potentiometers, rheostats, digital potentiometers, and their functions.

Although integrated circuits (IC) sit atop the world of electronics, the transistors within them do the bulk of the work. Within each IC are millions of transistors constantly switching on and off to allow the IC to complete its functions. Even if just one of the many transistors were to stop working, the IC could lose some or all of its capabilities.

Sensors are among the most critical parts of many devices and systems. When it comes to analyzing physical or environmental conditions, temperature is among the most important parameters. As such, when designing an electronic device or system that requires temperature measurement, designers have many options to select from. Two of the most common temperature-sensing technologies, which offer features and functionality for a wide range of uses, are negative temperature coefficient (NTC) thermistors, and resistance temperature detectors (RTD).

When managing an electrical circuit, resistors are components that serve to reduce current flow and adjust signal levels in order to further the safe and efficient distribution of power. Depending on the application that needs a resistor and its presented electrical ratings, a variety of resistor types and materials may be used in order to achieve varying operations and resistances. As one of the primary materials for manufacturing, carbon can allow for a number of robust resistors to efficiently manage the current loads of many different electrical systems.

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.

A resistor is a type of electrical component that can provide current resistance, benefitting electronic circuits of all types. With a resistor, current flow may be reduced, signal levels can be adjusted, voltages may be divided, and much more. As such, resistors are extremely common for the protection of electrical networks and electronic equipment. Depending on the application, there are a variety of resistor types that may be used, each providing their own unique benefits for various applications.

When operating an aircraft, it is always important to ensure that every system and component is well maintained to preserve airworthiness and safety standards. The aircraft jet engine in particular is a section that requires thorough maintenance as the extreme conditions that aircraft undergo during flight operations can cause damage and inevitable failure if left unchecked. In this blog, we will discuss why jet engine maintenance is important, how it is conducted, and more.

Aircraft engine baffling is important in ensuring the engine is properly cooled. Engine baffles and cowls are designed to provide an air-tight seal between the top and bottom of the engine. This seal ensures that cooling air is accurately directed through the engine, oil cooler, and engine compartment preventing the engine from overheating.

ADS-B technology (Automatic Dependent Surveillance Broadcast) is a rising solution in the world of aircraft control. It combines GPS, satellite, and computer processing capabilities with the goal of gradually phasing out the reliance on radar, a longtime cornerstone of aviation navigation. Instead of traditional radar, the ADS-B system determines its position via satellite navigation and broadcasts it, allowing it to be tracked. The information is received by air traffic control ground stations as a replacement for secondary surveillance radar, as a ground-based interrogation signal is not needed.

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.
