  WHIRLPOOL GALAXY FACTS 
  
The whirlpool Galaxy is a familiar one to stargazers and among the many close galaxy neighbors to our own MILKY WAY. Because of its shape, it was the first galaxy to be classified as a spiral by astronomers. Today,it interests astronomers due to its spiral structure and the interaction it appears to be having with its near neighbors, M51b.
WHIRLPOOL GALAXY PROFILE 
Designation:  M51a or NGC 5194
Type:    spiral       
Diameter:  60,000 ly         
  Distance:  23 Mly              
    Mass: 160 billion M
Constellation: Canes venatici       

FACTS ABOUT THE WHIRLPOOL GALAXY 
• The whirlpool Galaxy was first discovered in 1773 by Charles Messier, who was charting the skies looking for objects that might be confused with comets.

• In 1845, astronomer William parsons observed the galaxy pair with his telescope at Birr Castle, Ireland, and found the spiral structure of the whirlpool.

• The whirlpool and its companion, M51b have already passed by or through each other once as they dance through a cosmic merger. The smaller galaxy has been severely disrupted by the encounter, and the whirlpool's spiral arms are distorted.

• The whirlpool Galaxy is undergoing huge bursts of starbirth due to its ongoing encounter with its smaller companion galaxy.

• The whirlpool, like many other galaxies, has a supermassive black hole at its heart, surrounded by rings of dust. The core of the galaxy is quite quite active - making the Whirlpool what astronomers call a "seyfert galaxy".

• The whirlpool's companion called M51b, is a dwarf galaxy. Because it is being torn apart by the ongoing interaction, it cannot be easily classified.  Its current appearance makes it look like an irregular galaxy.

• A bridge of gas and dust ties the two galaxies together as they merge.

SURFACE MOUNT TRANSISTOR IN MOBILE PHONE & THEIR FUNCTION

Image
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.

Small Parts / Electronic Components of Mobile Phone and Their  Function                               The PCB of a mobile cell phone has several small parts or electronic components. When LEARNING MOBILE REPAIRING , it is important to learn and understand how to identity these small parts or electronic components and understand their function. Identification of these small parts on the PCB OF MOBILE PHONE is easy if you know and understand some of the basic rules. It is also important to understand what to do if any of these small components is faulty. Most of these electronic components are SMD  ( SURFACE MOUNT DEVICES) They don’t have any leads like thru-hole ELECTRONIC COMPONENTS .                                                                                                              Small Parts / Electronic Components of a Mobile Phone: Identification, Faults and Function: 1. Boost Coil Its size is little bigger than coil. It is found in black colour and look
