The vast majority of electrical systems in the United States are wired and designed for alternating current, or AC. Homes, office buildings, and businesses all run on AC. Most electronics, however, need direct current, or DC, to run properly. There are several different ways to convert AC to DC, but for this blog, we will focus on the use of diode bridges, or bridge rectifiers.

A carbon film resistor is an evolved form of the carbon composition resistor; it is smaller in size and capable of providing much better performance. It is a type of fixed resistor that uses carbon film to restrict an electric current to a certain level. It is constructed by using a ceramic carrier rod onto which a thin layer of pure carbon is deposited as a film. This thin carbon film acts as the resistive element. The ceramic substrate acts as the insulating material to heat or electricity.

In electrical engineering, a switch is used to interrupt current or divert it from one conductor to another. When an electrical contact is open, it means that the switch is off and not conducting because the contacts are separated; when an electrical contact is closed, it means that the switch is on and conducting because the contacts are touching.

Smartphones know to dim the screen and disable touch interaction before it comes into contact with a user’s ear— and they’re only capable thanks to a photoelectric proximity sensor. Proximity devices can to infer the presence of a variety of objects and materials without direct contact. The most common proximity sensors are inductive, capacitive, photoelectric, and ultrasonic.

Metal film resistors are one of the most common types of axial resistors. They use a thin metal layer as a resistive element on an otherwise non-conducting body. The first metal film resistor was manufactured in the 1930s by Dubilier.

Unless you’ve drastically tried to fix water damage on your computer or replaced the cracked screen of your smartphone on your own, you’ve probably never seen what a motherboard looks like or know what all the different parts do. But, if you’ve ever considered going into software engineering or computer science, perhaps you should at least know the difference between some components, for example, the FPGA and the microprocessor.

Memory cards are used every day to suffice all our electronic devices such as cameras, cell phones, and so much more. The most common form of memory is Flash memory because it is non-volatile meaning it can be removed from the device without losing data and reused by overwriting and erasing the data. We will be talking about all the different forms of memory cards and the capabilities.

Cliff Electronics has successfully created a range of XLR panel analogue connectors which are highly functional industry standard connectors. Their new model of mono and stereo jack will create a larger pool of consumers to be able to operate with. The XLR panel connectors are traditionally the three pinned analogue connectors which are mainly used for professional audio use. However, now there are many different pin variations which allow for numerous applications. The different patterned pins are specific to applications such as lighting, intercom, and more.

What are you going to do when it’s the dead of winter, and your power goes out? That electric fireplace is now useless as you try to scramble around the house to find enough blankets to keep everyone warm. What if you’re a principal of a school? The power goes out, so you must send all the kids home. As a result, you are losing a whole day of school and getting everyone behind. Instead of letting the weather or unfortunate events ruin your day try one of these new systems!
