Wireless power transfer is a process in which electrical energy is transferred from one system to another system through electromagnetic waves without using wires or any physical contact. In this post I have explained regarding how wireless power transfer works or the transfer of electricity through air without using wires. You might have already come […]

How a Relay Works – How to Connect N/O, N/C Pins
An electrical relay consists of a electromagnet and a spring loaded changeover contacts. When the electromagnet is switched ON/OFF with a DC supply, the spring loaded mechanism is corresponding pulled and released by this electromagnet, enabling a changeover across the end terminals of these contacts. An external electrical load connected across these contacts are subsequently […]
What is a Gunn Diode? How it Works?
Gunn diodes are semiconductor devices which are used to generate low-power microwave signals in a simple and low-cost manner. These have been in use for more than 60 years now. Gunn diodes can work with frequencies ranging from a few gigahertz to over 100 GHz. It was first discovered by J. B. Gunn of IBM […]
How MOSFET Works like a Switch
Now in our earlier talks we saw that the N-channel Enhancement-mode MOSFET or e-MOSFET works nicely when we supply it with positive input voltage, so this is very important to remember. This type of MOSFET has very high input resistance, almost close to infinity, and because of that we can use it easily like a […]
How an Accelerometer Works
In this post I will try to explain how an accelerometer works and also learn the specifications of a popular accelerometer ADXL335 in detail. If you are a tech enthusiast you would have came across the term called “Accelerometer”. This piece of technology made our smart phones really smart, many common home appliances, automobile, robotics, […]
How Shunt Regulator TL431 Works, Datasheet, Application
In this post I have explained how a shunt regulator IC works typically in SMPS circuits. We take the example of the popular TL431 device and try to understand its use in electronic circuits through a few of its application notes. Electrical Specifications Technically the device TL431 is called a programmable shunt regulator, in simple […]
