Before going to the details, you must understand what is a control system. What … [Read more...] about Open Loop and Closed Loop Control System (4 Practical Examples Included)
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. … [Read more...] about Miniature cells and Batteries – Silver Oxide, Mercury and Lithium Cells
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 the end … [Read more...] about Capacitors and Capacitance – Working, Unit, Types and Specification
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 the Constant Current Driver.As the name suggests, the constant … [Read more...] about Constant Current Driver Design based on LM317
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, resistance and … [Read more...] about What Are Current, Resistance and Voltage?
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) One commonly used schematic symbol for these LEDs is shown … [Read more...] about How Multicolor RGB (Red Green Yellow) LEDs Work?
A light-emitting diode (LED) is a diode that gives off visible light when forward biased. Light-emitting diodes are not made from silicon or germanium but are made by using elements like gallium, phosphorus and arsenic. By varying the quantities of these elements, it is possible … [Read more...] about 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 voltage of the circuit; digital voltmeters give a numerical display of voltage by use of … [Read more...] about Arduino DC Digital Voltmeter
