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 …
