INTRODUCTION The common emitter amplifier circuit makes use of a voltage divider circuit as seen in previous lessons on DC analysis. However‚ for the small signal analysis portion for this circuit‚ the objective is to analyze the input and output signals produced by the amplifier. Because of the resulting output signals‚ which will be discussed further in other sections‚ this amplifier is essential to AC appliances requiring a certain amount of voltage and current gains. II.

high voltage power from the generators of the electrical utility company. The purpose of the steel plant primary transformer is to step-down this voltage. The transformer thus provides high current‚ low voltage power for the EAF furnace. Large furnaces with transformers rated at 100MVA or higher is not uncommon. There are usually two stages to this process. The transformer first steps-down the voltage from high to medium levels. There are different standards for a "medium-level voltage" in

CHAPTER 1 INTRODUCTION This project is mainly used to save power automatically instead of doing manual by using IR sensors The main consideration in the present field technologies are Automation‚ Power consumption and cost effectiveness. Automation is intended to reduce man power with the help of intelligent systems. Power saving is the main consideration forever as the source of the power(Thermal‚ Hydro etc.‚)are getting diminished due to various reasons. Wireless communication

INTRODUCTION For years‚ infrared LED has been merely a system for piping light around corners and into the inaccessible places to allow the hidden to be lighted. But now‚ infrared LED has evolved into a system of significantly greater importance and use. Throughout the world‚ it is now being used to transmit voice‚ television and data signals as light waves. Its advantages as compared with conventional coaxial cable or twisted wire pairs are manifold. As a result‚ millions of dollars are being spent

clockwise direction‚ the right secondary windings will be in the anti-clockwise direction‚ hence the net output voltages will be the difference in voltages between the two secondary coil. The two secondary coil is represented as S1 and S2. Esteem iron core is placed in the centre of the cylindrical former which can move in to and fro motion as shown in the figure. The AC excitation voltage is 5 to 12V and the operating frequency is given by 50 to 400 HZ. Working of LVDT: Let’s study the working of
