In an RC circuit, a combination or R (resistor) and C (capacitor) is used in specific configurations in order to regulate the flow of current, for implementing a desired condition. One of the main uses of a capacitor is in the form of a coupling unit which allows AC to pass but blocks DC. In […]

How Thyristors (SCR) Work – Tutorial
Basically an SCR ( Silicon Controlled Rectifier) which is also known by the name Thyristor works quite like a transistor. What SCR Stands for The device gets its name (SCR) due to its multi layered semiconductor internal structure which refers to the “silicon” word in the beginning of its name. The second part of the […]
How Stepper Motors Work
In this post I have explained about stepper motor. We will be exploring what stepper motor is, its fundamental working mechanism, types of stepper motor, stepping modes, and lastly its advantages and disadvantages. What is stepper motor? Stepper motor is brushless motor; its rotating shaft (rotor) completes one rotation with a determined number of steps. […]
How Supercapacitors Work
In this post I have explained what a supercapacitor is, how closely similar or different to an ordinary capacitor, where it is used and we will be doing comparison between batteries and super-capacitors to find out which one of them is superior. Let’s understand the basics of an ordinary capacitor. How Ordinary Capacitor Works A […]
How Brushless DC (BLDC) Motors Work
The post comprehensively details the basic operating concept of brushless DC motors also called BLDC motor. Difference Between Brushed and Brushless DC Motors In our traditional brushed motors brushes are employed in order to switch the central moving rotor with respect to the surrounding stationery permanent magnet stator. Brushes become imperative because the rotor is […]
How Mosquito Traps Work
Mosquito and other forms of fly trap mechanisms work by making use of luring techniques for attracting the insects, which involve carbon dioxide gas, body odor simulators and ultraviolet lights. These traps become very useful in areas which may be highly infested with mosquitoes, however due to its high costs such traps are not very […]
