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 …
A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the …
What is ROM? ROM stands for Read-only Memory. It is a type of memory that does not lose its contents when the power is turned off. For this reason, ROM …
A servomotor is also defined as a rotary actuator that allows for very fine control of angular positions. This article explains controlling a servo motor with Arduino in detail. Many …
In this article, you will study the concept of electric potential, potential difference (PD) and electromotive force (EMF) and the difference between them. Just as a body raised above the …
Basically, a capacitor is formed from two conducting plates separated by a thin insulating layer. There are different types of capacitors that are manufactured in many forms, styles, and materials. Understanding …
The automatic light controller offers energy saving and convenience in the areas with a photosensor (LDR). LDR senses the ambient light conditions in the surrounding area and switches ON-OFF the …
The term microprocessor and microcontroller have always been confused with each other. Both of them have been designed for real-time application. They share many common features and at the same …
Digital code locks are most common in security systems. An electronic lock or digital lock is a device which has an electronic control assembly attached to it. They are provided …
