What is DC Ammmeter? A DC ammeter is the instrument used for measuring the direct current (DC) flowing through an electrical circuit and is connected in series to the circuit
Electrolytic capacitors are one of the most commonly used types of capacitor. Their capacitance values range from about 1 μF to 6800 μF. Electrolytic capacitors are more popular because the
An Electrical Fuse is a vital component of any equipment. It is used as an indicator of a defect in the system. It protects the equipment from overcurrent or overloading.
PCB assembly is the process of assembling electronic components on a Printed Circuit Board (PCB). In this article, you will learn the PCB assembly process and its equipment in general.
Since electronics were created, electronic projects have become one of the most popular hobbies that existed. While the tools and components have become so advanced these days, the enthusiasm and
Charging and discharging are the two main effects of capacitors. In this article, you will learn about charging and discharging a capacitor. When a voltage is applied on a capacitor
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 (LED)
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
No electronics can run without power, to be precise a low voltage DC power, and a power supply unit is a device which is specifically meant for fulfilling this purpose.
