Ultrasonic technologies are used in various industries, from healthcare to environmental monitoring. However, few people are aware of this technology and how it works. One of the products of ultrasonic technology is the ultrasonic transducer. Are you planning to buy an ultrasonic transducer? This article is perfect for you. We are going to discuss everything…
When it comes to choosing a Valve Regulated Lead(VRLA) battery for your project, you probably have a lot of questions running through your mind. They include, how long will my VRLA battery last, where can I find more batteries when I run out, and what are the best batteries for my project? That’s why we’ve…
You might have noticed that a small gadget like a digital watch, garage door opener, or even remote control is powered by a tiny, disk-shaped battery. The teeny-tiny cell you’re looking at may be a CR1632. They used to be contaminated with dangerous metals like silver and mercury. They’re now manufactured with a negative material…
As you may know, Resistors are omnipresent in electronic equipment and are common elements of electrical networks and electronic circuits. Variable resistors are resistors with variable resistance values. Changing the values of currents and voltages in various electrical circuits is occasionally necessary. For example, changing the volume of sound and brightness on television, the volume…
What comes into your mind the moment you think of mouse bites? You would think of many tiny holes scattered all over the surface of an object. Take a look at any brand new PCB; you will notice it has numerous holes that seem to be perfectly drilled and arranged. Now try to imagine such…
What comes into your mind when you hear the term “relay?” To most of us, we assume it is something that receives and passes over an object. In most electric circuits, relays act as switches. A typical relay is a closed electrical circuit that is used to switch electric currents from one circuit to another.…
A 94v0 circuit board may be unfamiliar to you. Some people (engineers and other professionals) periodically ask if the board is relevant to their electrical systems. Alternatively, you might be curious why they were chosen over normal PCBs. The lack of understanding regarding the 94v0 circuit board is the source of all knowledge. You’ll need…
Multilayer PCBs have become quite popular in various industries throughout the years. Multilayer PCBs, such as 4-layer PCBs, 6-layer PCBs, and so on, are readily available today. PCBs with six layers have become commonplace in small wearable devices and other mission-critical communication equipment. What is it that makes them so popular? What distinguishes them from…
Image credit: pinterest.com You might already know that PCB and PCBA both stand for printed circuit board, but you might not know exactly why these words are so similar. PCBA and PCB are both abbreviations for printed circuit boards, but what’s the difference? First of all, let’s look at the dictionary definition of PCB. PCB…
Batteries are designed to provide the power needed to run various devices, allowing you to take your favorite gadgets with you. Consumers today have access to a wide range of battery options, including nickel-cadmium batteries. What is Nickel-Cadmium Battery A rechargeable nickel-cadmium battery (NiCad or NiCad) is used in portable computers, drills, camcorders, and other…
