SURFACE MOUNT TRANSISTOR IN MOBILE PHONE & THEIR FUNCTION

Surface Mount Transistor in Mobile Phone and Their Function Surface Mount Transistor or SMT Transistor is an SMD electronic component  made up of semiconductor material like silicon or germanium. There are 2 types of Surface Mount Transistors: NPN Type PNP Type Terminals of a Transistor There are three terminals of a surface mount transistor or thru-hole transistor: Ammeter (E) – Flows current on receipt of forward bias. Electrons are emitted in NPN transistors whereas PNP transistors emit ‘ holes ’. Collector (C) – The terminal of the transistor which receives the emitted electrons or holes. Collector always works or reverse bias mode. Base (B) – The layer between ammeter and collector is called base. Base displays the property of showing low resistance in ammeter junction forward bias and high in collector junction reverse bias. Facts about Transistor Indicating Character : Q or V, TR Function : Switching, Amplification, Regulating Voltage.

Five Simple Tips to Increase the Life of Your Phone's Battery    Properly charging your smartphone is essential for maintaining the health of your battery, and ensuring better battery life and increased safety in the long run. Simply plugging your phone in as soon as you get home and leaving the charger on until you leave in the morning is not the right solution. Since there is a lot of different advice floating around on how to charge your phone, we decided to get you tips to get the most out of your smartphone's battery from the guys who built. Here's what they told us: 1. Don't let your phone overheat Heat is perhaps the worst enemy of lithium-ion batteries, the kind most smartphones use. "You should take basic precautions like not keeping your phone on the dash board of the car where it will get a lot of direct sunlight," You should also avoid charging your phone while playing graphically intensive games, because that will also raise the temperatur

BLACK HOLE MYSTERY DATING BACK 40 YEARS SOLVED BY "BEST EVER" SIMULATION  A team of astrophysicists from Northwestern University, Oxford University, and the University of Amsterdam, used graphical processing units to crunch large sets of data and simulate how black holes interact with their accretion disks. The first photo of a black hole was captured in APRIL this YEAR PARIS: Scientists on Thursday unveiled the most detailed simulation of a black hole yet, solving a mystery dating back more than four decades over how the star-devouring monsters consume matter Coming fresh on the heels of the first ever photo of one of the giant objects, which are scattered across the Universe, astrophysicists are now several steps closer to understanding how they form and develop. A black hole is born when a large star collapses in on itself. Far from being a "hole", they are instead incredibly dense objects with a gravitational pull so strong that nothing, not even lig
