Did you wonder how charge get stored in a dielectric material. Is it really possible? Yes, it is possible for dielectric materials such as air or paper to hold an …
The open-loop control system and closed-loop control system are the two types of control systems that you will learn in this article with the help of 4 practical examples from …
In recent years, cells and batteries—especially cells—have become available in many different sizes and shapes besides the old cylindrical cells, transistor batteries and lantern batteries. In this article, you will …
The directed flow of free electrons (or charge) is called the electric current. The electric current may be classified into three main types: Steady current (DC Current) Varying current Alternating …
In this article, you’ll learn about electrical components that oppose the flow of AC by temporarily storing energy as electric fields. These devices are called capacitors, and their action is …
Using a resistor to limit the current can be used for small LEDs. For such low power LEDs, where the supply current is not critical it works okay. But for …
Voltage, current, and resistance are three properties that are fundamental to almost everything you will do in electrical and electronics engineering. They are intimately related. In this article, we used …
A Light Emitting Diode that emits one color when forward biased and another color when reverse biased is called a multicolor RGB LED. Related Article: Working of Light Emitting Diode …
