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 fascination for the hobby itself remain true as ever. With …
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 it puts a charge in the capacitor. This charge gets …
[et_pb_section admin_label=”section”] [et_pb_row admin_label=”row”] [et_pb_column type=”4_4″][et_pb_text admin_label=”Text”]It is possible for dielectric materials such as air or paper to hold an electric charge. This is because free electrons cannot flow through an insulator. However, the charge must be applied by some …
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 your daily life. Before going to the details, you must …
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 learn about three types of miniature cells and batteries. Silver …
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 current (AC Current) Read: What are Current and Voltage? Steady …
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 known as capacitance. This article discusses capacitors and capacitance. By …
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 high-power Light Emitting Diodes, a better way is to use …
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 water in a river analogy to explain what is current, …
