Soldering is the basic process required in every electronics industry and an individual should have knowledge of soldering if he is an electronics engineer. Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint, the filler metal having a lower melting point than the work piece. Soldering differs from welding in that soldering does not involve melting the work pieces. I don't think you should go deep in theory related to soldering but you should know about the basic equipment required to soldering. Equipment: 1. Solder Iron 2. Solder Wire   It melts and solder the components on PCB 3. Solder Flux   It removes the impurity from the solder wire during melting. it lowers the melting point of solder wire 4. General Purpose PCB   It is a General Purpose PCB on which objects are mounted. Applications: - Soldering is used in plumbing, in electronics...

Sensors are like detector which detects physical quantity and converts that quantity into a signal that can be read by an electronic instrument. It is a device which measures and responds to a signal. A sensor's sensitivity indicates how much the sensor's output changes when the measured quantity changes. Sensors are a new solution for measuring currents and voltages needed for protection and monitoring in medium voltage power systems. Certain strong trends have been present during the whole period of electrical equipment manufacturing: a continuous reduction of equipment size , a continuous improvement of equipment performance and a continuously grooving need for standardization . Sensors are the part of our life and they are used in every day life devices we use like proximty sensor in smartphones, accelerometer sensor, motion detector etc. The use of sensors make the different devices to function smartly, more accurately and make it possible to develop Intel...

All speakers feel a little nervous, at least when starting a presentation and body language is considered the most important factor while addressing in the front of audiences. That is quite natural.

Resistor is a component that resists current to flow through the circuit. Resistors are probably the easiest component to test with a multimeter. Through Color band: Before you can test a resistor, you need to know its strength and tolerance. Resistors are color-coded. If you look at a resistor, one end should have a gold , silver , or white band. These 3 color coding gives error value ±10%, ±5%, and ±2% respectively. Turn the resistor so that this band is to your right. That band represents the resistor’s tolerance. Before I discuss tolerances, you need to know how to read a resistor’s values. You begin by translating the colored bands into numbers and recording those numbers. For the first and second colored bands, the values are as follows: Black = 0 Brown = 1 Red = 2 Orange = 3 Yellow = 4 Green = 5 Blue = 6 Violet = 7 Grey = 8 White = 9 There is best and easy way to learn above color bands on fingertips. Learn the color coding in this way - BBROY 'G...

Test your LED using Digital Multimeter by simply connecting lead to cathode-anode ends of LED. LED is a type of diode that emits light when external voltage is applied. Steps to Test LED: Connect the black lead to the COM terminal on the multimeter. Connect the red lead to the Ohm terminal , unless your particular model differs. Turn the dial to the diode symbol on the multimeter. This allows for electric current to travel in one direction (the arrow) and not the other. Choose a regular red LED. Connect the black probe to the cathode end of the LED, which usually is the shorter end and/or cut flat at its bottom. Connect the red probe to the anode end of the LED. You will find that LED will light up, showing it is correct to use in your project. LED will light due to the battery power of multimeter and completing the connection. LED Forward Voltage Drop The value displayed on your multimeter is called the forward voltage drop. This indicates the quantity of vol...

This technique is for B.tech students who get admitted to Guru Gobind Singh Indraprastha University. You should now that there are 3 internal exams or sessionals are conducted before End term or final exams. Out of 3 internal exams student have to appear in 2 internal exams to get internal marks. Each internal exam subject weight-age is of 30 marks and scoring out of 30 is divided by 3 to get the score out of 10. So, with 2 internal exam, total marks comes out to be 20 and other 5 marks are based on attendance and impression on your subject teacher so don't mess with him. These 25 marks are considered precious than End term. As, considering final year student, One should maintain at least 18 or 18+ marks out of 25 to get easily passed in your final examination.

Every student uses Smartphones has a question - How touchscreen works?   It is simple to learn a Smartphone screen works. It is almost similar in all types of touchscreen phones. Let's start with the Introduction: Touchscreen-  It is the 2-dimensional electronic sensing device that detects the presence as well as the location of the object eg. finger or stylus, touched on the display screen area. When we touch eg. our finger on the display of a Smartphone, The uniform electrostatic field lying beneath the touchscreen of the phone, gets disturbed and sends a signal with the coordinates location to the processor. The processor analysis the point of location and presence and perform the function accordingly stored in it. The program of every function is defined in the processor by the developers so that it can perform and analyze accordingly. See the Below picture to understand the better working of a touch screen..
