Capacitors are electrical components that are found in many circuits, capable of storing electrical energy within an electrostatic field. As a passive electronic component with two terminals, capacitors typically serve the role of holding energy that is needed for a quick release, such as for the flash of a camera. Most capacitors are assembled from two parallel plates that are separated by a dielectric, that of which is a form of insulating material. In the market, there are various forms of capacitors that one can procure, the most common being electrolytic and ceramic capacitors. While the biggest difference between the two is the dielectric material of choice, there are other variations that are important to consider.

“Thermistor” is the name given to thermally sensitive resistors whose primary role is to show an accurate change in electrical resistance in response to changes in the surrounding temperature. They are made of semiconductor materials which exert less resistance in either increased or decreased temperatures depending on the device. In addition to being very small for use in tight spaces, thermistors respond quickly to temperature changes, making them the most sensitive temperature sensors out there. Both negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors’ values change when exposed to shifts in temperature, but the way in which they are impacted makes them suited for different applications.

When working in manufacturing processes involving metals, it is often very important that one knows the difference between soldering and desoldering. While soldering involves the process of joining pieces together by establishing a joint, desoldering is the opposite process where the solder is removed from a joint. Both processes can be very important for a number of applications and needs, and they both involve separate sets of equipment and safety instructions. Additionally, the practice of soldering and desoldering can be tricky to master, and both practices are known for their learning curves. To help you better understand how each is carried out and when, we will briefly discuss soldering and desoldering in this blog.

Commonly used for laboratory and industrial means, potentiometers and rheostats are two different types of variable resistor that are used in various electronics. To ensure networks are operating at peak efficiency, both devices are designed to control current and voltage flowing through a circuit by the means of actuating one or more knobs. However, while they may perform similar functions, they should not be interchanged with one another unless specified because of their individual and particular construction. To better understand how potentiometer and rheostat components function separately, we will go into detail on when each should be applied, alongside what to look for when choosing the appropriate part.

In the realm of computer technology, memory serves as the means for a computer to store all the data and instructions that it needs to operate as intended. Memory components are required for a computer to function, and they are utilized by the operating system, hardware, and software. As memory can come in different forms, each with varying functionality, it is important that one familiarizes themselves with common options before attempting to build their own computer or purchase parts for upgrades.
