CHAPTER I ------------------------------------------------- INTRODUCTION 1.1 Introduction Portable electronic devices are very popular nowadays. As the usage of these portable electronic devices is increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless

Microstrip‚ Stripline‚ and CPW Design Iulian Rosu‚ YO3DAC / VA3IUL‚ http://www.qsl.net/va3iul In the first years of microwave development the Rectangular Waveguide become the dominant waveguide structure largely because high-quality components could be designed using it. One of the main issues was its narrow bandwidth due to the cut-off frequency characteristic. Later‚ researchers try to find components that could provide greater bandwidth and possible miniaturization‚ and therefore they examined

conversion ratio‚ the interleaved buck converter can be used for high step-down and high frequency applications. The main features of the converter also include lower switch stress and lower output current ripple. The topology consists of two input capacitors which help in the reduction of the voltage stress across the switches. One-cycle control (OCC) technique is used to provide the switching pulses for the switches. The simulation has been

What’s the difference between resistance and resistivity? Resistance is the obstruction offered to the flow of current by a conductor. Resistivity is the obstruction offered to the flow of current by UNIT AREA OF the conductor. So basically‚ resistance is the property of the object (say a copper wire)‚ whereas resistivity is the property of the substance (copper). And so resistance depends upon the properties of the object. Whereas resistivity depends upon the properties of the metal.

An ideal air-filled parallel-plate capacitor has round plates and carries a fixed amount of equal but opposite charge on its plates. All the geometric parameters of the capacitor (plate diameter and plate separation) are now DOUBLED. If the original energy stored in the capacitor was U0‚ how much energy does it now store? C= Aε/d wher C= capacitance‚ A= area‚ d= distance between plates let original radius be r so original area A= πr2 noe r is doubled and d is also doubled so new area A2=π(2r)2=
