Components are intended to be connected together‚ usually by soldering to a printed circuit board‚ to create an electronic circuit with a particular function (for example an amplifier‚ radio receiver‚ or oscillator). Components may be packaged singly (resistor‚ capacitor‚ transistor‚ diode etc.) or in more or less complex groups as integrated circuits (operational amplifier‚ resistor array‚ logic gate etc.) Components Very often electronic components are mechanically

AN OVERVIEW OF THE Shed: This shed was set up in Feb. 1976 by Railway Electrification Organization as a part of Tundla – Delhi electrification scheme and was designed to home 50 electric locomotives at an initial cost of 1.5 crore. The prime objective of setting up this shed was to maintain Electric locomotives required for hauling important mail/express trains on Delhi – Howrah section. The initial holding of the shed was 34‚ all of which were WAM4. At present‚ holding has increased to 138

TGS 813 is a general purpose Sensor that has good sensitivity characteristics to a wide range of gases. This device is designed to operate with a stabilized 5V heater supply and a circuit voltage depends on the design. The most suitable application for the TGS 813 is the detection of carbon gases‚ which makes it an excellent Sensor for gas leak detectors. The initial stabilization time of the TGS 813 is very short and the relative and elapsed characteristics are very good over a long period of Operation

Short Selling: Assessing New Zealand’s regulatory regime and future development 1. Introduction 1.1 The recent global economic crisis has seen an unparallel shift in the global perception of free markets. Regulators around the world have adopted a more strict regulatory approach to markets than seen previously. Short selling is been given particular attention from authorities due to its speculative use and questionable moral nature. As in the past‚ “short selling has been a favourite whipping
