Potentiometer: Definition, Types, And Working Principle What is a Potentiometer? A potentiometer (also known as a pot or potmeter ) is defined as a 3 terminal variable resistor in which the resistance is manually varied to control the flow of electric current . A potentiometer acts as an adjustable voltage divider . How Does a Potentiometer Work? A potentiometer is a passive electronic component . Potentiometers work by varying the position of a sliding contact across a uniform resistance. In a potentiometer, the entire input voltage is applied across the whole length of the resistor , and the output voltage is the voltage drop between the fixed and sliding contact as shown below. A potentiometer has the two terminals of the input source fixed to the end of the resistor. To adjust the output voltage the sliding contact gets moved along the resistor on the output side. This is different to a rheostat , where ...
The pin diagram of 8051 microcontroller looks as follows − Hello friends I am Abhinandan your friends So toady topic is pin diagram of 8051 microcontroller hai Aur sath hi kaise jaldi yaad rahe ye bhi bataugaa ok so start a blog And requested for all friends to share my blog and like also. Pins 1 to 8 − These pins are known as Port 1. This port doesn’t serve any other functions. It is internally pulled up, bi-directional I/O port. Pin 9 − It is a RESET pin, which is used to reset the microcontroller to its initial values. Pins 10 to 17 − These pins are known as Port 3. This port serves some functions like interrupts, timer input, control signals, serial communication signals RxD and TxD, etc. Pins 18 & 19 − These pins are used for interfacing an external crystal to get the system clock. Pin 20 − This pin provides the power supply to the circuit. Pins 21 to 28 − These pins are known as Port 2. I...
Did You Know, You Can Change The Instagram Icon On Your Android Phone And Apple iPhone? To set this up on an Android phone and an Apple iPhone, you must first update the Instagram app and ensure you are running the latest version. There is a secret menu in the app that you need to find your way to and choose from as many as 13 new icons that are available. Instagram users, good news! You probably had not realized this all along, but you can actually change the logo of the Instagram app on your Android phone or the Apple iPhone . There is a secret menu in the app that you need to find your way to and choose from as many as 13 new icons that are available. Some of these icons are a tribute to the pre-launch icons and the ones we have seen with the social media app in the past decade, while others follow a more modern design manual, including the Dark icon. At this time, the icon options include the Original icon from 2010, as well as the Codename one th...
